Question

define 1 volt Express it in terms of s i unit calculate the amount of energy consumed in carrying a charge of one column through battery of 3 volt

Answer 1

Heya!!

-------------------------

Electric potential difference between two points said to be 1 volt if 1 joule of work is done in bringing a positive unit charge from high potential to low potential.

Since V = W/Q

=) 3 = W or E / 1

=) 3J = E

Hope it helps uh :)
