Sir how can one explain with the help of an analogy to a grade 10th student the reason behind not getting a shock on touching the neutral wire of the household AC circuit, even though the current flows alternately through live as well as neutral wires.
A cable of resistance 12 Ohm carries electric power from a generator producing 250 kilowatt at 10,000 volts. Calculate the current in the cable.
Solution
using P=VI
I=25A
but using P=I^2R
250000=I^2×12
I =500/root 12 Amps
What is the reason for the different...
