Seeing that Li Qinghe really didn't want to stay, Aunt Zhang could only leave with regret and go back to do housework.
You Fengxia did not leave, but watched Li Qinghe working from the side. "Master Li, are you an electrician at the steel mill?"
"Yes, from the steel mill." Li Qinghe responded casually.
"Level 1."
"Level one? Then the salary should be more than 30, right?" You Fengxia was a little disappointed, but still asked.
"Thanks to my dad, I got 36.5 yuan."
"Your father?" You Fengxia was stunned. How could this salary be related to your father?
"My father is a martyr." Li Qinghe replied casually, then frowned slightly. There is nothing wrong with the circuit.
And if the light can be turned on, it means there is electricity, but if the bulb is burned out, then there is a problem somewhere else, resulting in unstable voltage.
Li Qinghe moved a stool, replaced the light bulb with a new one, tried the pull cord, the light bulb lit up successfully, and then turned it off.
After coming down, I took the tools and started testing.
"Turn on the light."
"Ah? Oh, okay."
You Fengxia's heart was pounding, but she suppressed the excitement on her face and went to turn on the light obediently.
Li Qinghe found that the voltage was a bit unstable, and then he started looking along the line, all the way outside the house. He discovered that the wire connected to the house was very thin and very long, and it had to be wrapped around several times before it could be connected to the house.
Li Qinghe's eyelids twitched. Which genius came up with this connection?
Not only is the wire you used thin, but you also wrapped it around so many turns. It would be strange if the voltage could be stable.
Electricity transmission involves consumption. Your wire is so thin, the amount of electricity it transmits is not much, and it is so long, so won't it consume more?
"Okay, turn off the lights." He turned around and shouted into the house.
"Have you found the problem?" You Fengxia turned off the lights and asked curiously. The electrician she had hired earlier had been busy for a long time and only said that everything was normal.
Li Qinghe nodded, "I found it, it will be ready soon."
After saying that, he found the power switch and turned it off. Then he moved a stool and took the wire he brought with him to replace the original wire.
He turned off the switch and said to You Fengxia, "Try turning on the light again."
"Oh, okay." You Fengxia nodded blankly, wondering, "Is it that simple?"
Turning on the light, Li Qinghe began to check along the line again. Sure enough, the voltage had stabilized. He tried turning the switch on and off several times and found no problem.
He clapped his hands, "Okay, it's solved."
"So fast?" You Fengxia was a little disappointed. She wanted to stay with Li Qinghe for a while longer.
Li Qinghe packed up his tools and said with a smile: "The really difficult part is finding the problem. Once you determine where the problem is, it will be easy to solve it."
