how much energy is given to each coulomb of charge passing through 6V battery ???
here, Potential difference= 6V
Charge of electron= 1 coulomb
Now, for every second of time 1 coulomb passes through conductor, Therefore,
Current= 1A
Now, Power= V*I
=> P= 6*1 W
=> P=6W
Now since 6 watt is the power then each coulomb of charge is provided with 6 Joules of energy per second.
