The current passes through the spiral filament, which is not conducive to heat dissipation, causing the filament to be in an incandescent state and produce light, but most of it is still converted into heat energy.
"Isn't it just a metal wire like a spring?" Sanbao understood the reason. The wire he removed from the motorcycle now contained very thin copper wire, but it seemed that copper wire was not suitable for use as a heating device.
, then the rest is the thinner wire.
Sanbao was so excited to figure it out that he didn't sleep well all night. Early the next morning, he asked Qu Changlin to find ways to go to Xiji Town and the county to buy batteries and light bulbs, as well as the thin wire he wanted.
Su Yuan learned that Sanbao was preparing to make an electric detonator. He knew the power of this kind of explosion on the battlefield, so he gave him great support. Sanbao had a few light bulbs that were difficult to obtain. At this time, the Japanese were interested in the battery.
Materials such as light bulbs and light bulbs are under control and are generally difficult to obtain. Sambo can only put what it has at hand into trial production first.
Su Yuan got a file for him. With this Sambo, he could carefully file open the glass of the light bulb, then pour gunpowder into it and seal it. Sambo connected the light bulb filled with gunpowder to the wires, and then put it into the mine.
The landmine was built, and the next step was to see the effect of the explosion. Sanbao didn't want to waste what he had worked so hard to create, so he decided to go directly to the battlefield and experiment with the Japanese.
This time, Sambo killed two birds with one stone. He still used the method used last time to cut off the Japanese wires and communication lines, but this time instead of cutting off the wires, he cut off all the wires, so that there would be enough detonating wires, and Sambo asked everyone to
Plan out the telephone poles and throw them on the roadside.
Next to a telephone pole pit, Sanbao planted five landmines, large and small, in a circle, and then led the connected wires to hide while retreating to the ambush site and began to wait.
The Japs learned their lesson from the last ambush, and this time they sent a car with seven or eight Japs out. The Japs coming along the road soon saw the telegraph poles where the wires had been cut and thrown to the roadside.
A Japs were on guard with a machine gun on the roof of the car, while the other Japs were busy erecting telephone poles. They saw four or five Japs right in the mine circle they had laid. Before the Japs could pick up their shovels and prepare to fill the soil, Sambo was already there.
Connect the two wires to the battery nearby.
At the same moment, the light bulbs in the mines heated up at the same time, and five mines were detonated at the same time. In a deafening explosion, smoke and yellow dust suddenly rose up like a huge garland, covering all the surrounding Japanese soldiers, and the smoke
Countless broken glass, iron nails and tiles burst out in all directions, and the screams of the Japanese were heard in the smoke...
The smoke had not dissipated, but the soldiers in ambush saw the newly erected telephone pole falling down, and the direction it fell was the Japanese car. The Japanese machine gunner on the car had not yet woken up from the explosion, and he lowered his head
His head was sheltered from the smoke and dust, but a gust of wind suddenly came to his ears. Before he could raise his head, the falling telegraph pole had hit his head hard...
The smoke had just cleared, and the Japs driver in the car had clearly seen the tragic scene in front of him, "There is an ambush from eight directions!" As soon as this idea appeared in his mind, he panicked and took care of his unidentified accomplices, so he immediately launched
The car wanted to run away.
Sanbao did not expect that the explosion would be so violent, and he even imagined that it might not succeed, so before that he ordered the soldiers who were following him to hide. Especially when he saw the Japanese machine gunners on alert, he had no intention of ambush the enemy.
Sanbao, who was watching the explosion effect, saw four or five Japs falling down after the smoke from the explosion cleared. The Japs machine gunner also had his brains exploded and was lying on the roof of the car. He was not willing to let go of such an opportunity. Seeing the Japs'
The car was moving. He immediately shouted: "Aim at the Japanese driver and hit me!"
Amidst the ping-ping-pong-pong shooting, the Japanese car was still moving. Sanbao couldn't hold it anymore and immediately rushed forward with a gun. When he rushed to the road, the Japanese car had already driven dozens of meters away. He was chasing him.
Unable to get on, Sanbao angrily raised his gun and fired repeatedly at the car that was driving away.
But I saw the car starting to sway left and right on the road. Finally, the car hit a telephone pole on the side of the road and stopped.
Shanzi, who caught up to him, said in surprise: "Platoon leader, you are so powerful!"
"What nonsense are you talking about? Go and have a look." Sanbao shouted. The two men stepped forward with guns raised. Sanbao opened the car door. The Japs driver tilted his head and rolled out of the car. He was hit by several bullets.
The bullet persisted until it reached here before dying.
"Platoon leader, there are two more alive here." The soldiers who followed behind shouted around the crater.
But Sanbao was wandering around the car excitedly. He said excitedly to Shanzi: "Now we have everything, gasoline, wires, light bulbs, haha..."
At this moment, Sanbao suddenly saw a shivering Japs crawling under the car. It was the Japs who set up the wires. He was leading the wires here. He saw the fighting over there and wanted to climb onto the oncoming car.
, but the car hit here, and he was so frightened that he hid under the car.
"Get out!" Sanbao shouted. The Japanese didn't know whether he didn't understand or was frightened. He held his head and refused to come out.
The impatient Shanzi dragged his legs out. Looking at the dusty Guizi Sanbao, he felt happy. He was worried about how to deal with this car. He immediately shouted: "Yours, do you know how to drive?"
The Japanese just raised his hands and muttered, "Platoon leader, he doesn't understand what you are saying." Shan Zi laughed from the side.
"I don't understand, didn't the Japs say that?" Sanbao said. He pulled the Japs to the car door and dragged the dead Japs out. Then he pointed at the steering wheel and gestured with his arms, "You understand."
."
Only then did the Japanese man understand and shouted, "Get in the car!" Sanbao ordered happily.
