Find the voltage change when (a) an electric field does 12 J of work on a 0.0001-C charge; (b) the same electric field does 24 J of work on a 0.0002-C charge.

Solution 9P Step 1 of 3: Work done on a charged particle by applied electric field is known as electrical work. The electrical work per unit charge , when moving a test charge between two points , is known as the voltage between two points. The relation between voltage change and work is, W V = Q Where V is voltage change , W is electrical work on charge Q.
