Voltage of lighting circuit in China
The 50 small lanterns have the same voltage at each end, and the voltage at each end of the lantern is zero
The total voltage of a series circuit is equal to the sum of the voltage of each series element. The voltage across the series circuit is in direct proportion to its resistance,
The series circuit current is equal, 50 lights are connected in series, and the current flowing through them is equal, which is 200mA=0.2A;
The appliances do not interfere with each other. They can work independently. They are connected in parallel;
The voltage of lighting circuit in our country is 220V;
