How much energy is given to each coulomb of charge passing through a 6 V battery?

Text Solution

Verified by Experts

Here the term, each coulomb. means every 1 coulomb.. So Q=1 coulomb, potential difference V = 6 volt, Energy = work done, W = ?
Now, W = VQ
=`6V xx 1C`
`= 6J`
Since the work done on each coulomb of charge is 6 J, 6 J energy is given to each coulomb of charge passing through a 6V battery.s
