Question

How much charge does a 9.0 v battery transfer from the negative to the positive terminal while doing 21 j of work?

Answer 1

2.3333 Coulombs

Step-by-step explanation

The average work done to move by a battery is given by:

∴ Work done = QV

Where Q is the number of charge and V is the voltage from the cells.

21 = 9Q

21 = 9Q

Q = 21/9

= 2.3333 Coulombs
