Voltage of lighting circuit in China

Voltage of lighting circuit in China

220 v

Which is more dangerous between the voltage of high voltage wire and that of lighting circuit? Why?

Because electric shock depends on the current, not the voltage
See the supplement
If other conditions are the same, of course, the voltage of high-voltage wire is more dangerous, because the resistance is the same, the voltage is high and the current is large
In addition, I'm a doctor with a high level

1. The voltage of a dry battery is () v. the voltage for human safety is () v
1. The voltage of a dry battery is () v. the voltage for human safety is () v. in order to use the switch to control the lamp () connection, and in order that the work of various electrical appliances in the room is not affected by each other, they must () connection. 2. There is a section of conductor. When the voltage at both ends is 2V, the current passing through it is 0.5A, and the resistance of this section of conductor is () Ω

1. The voltage of a dry battery is (1.5) v. the voltage of human body safety is (not higher than 36) v. the electric lamps are controlled by switches (in series); the work of various electrical appliances in the room is not affected by each other, and they must be (in parallel). 2. The resistance of this section of conductor is (4) Ω

All the time, the dial of the electric energy meter is "220 V, 5 A, 3000 turns per kilowatt hour". The maximum power that the meter can use is in the lighting circuit of watt; if there is only one watt in the circuit
When the 100 watt electric lamp works, the electric energy turntable turns around in ten minutes; the rule of fuse behind the electric energy meter should choose the rated current of ampere!

100W=0.1KW
10 minutes = 10 / 60 = 1 / 6 hours = 1 / 6 (H)
The energy consumption of 100 watt electric lamp in 10 minutes is w = Pt = 0.1 * 1 / 6 = 1 / 60 (KWH)
3000 laps per kilowatt hour is 1kwh for the meter to run 3000 laps
For 1 / 60 (KWH), the number of turns is 3000 / 60 = 50
According to the parameter of the electric energy meter, 220 V, 5 A, the rated current selected by the fuse should not exceed 5 A, otherwise the electric energy meter will be burnt out, so choose 5 a!
