Question

1. If the voltage on a positive and a negative region on the paper is 5.0 V, how much work woulld be needed to move 2.0 C of charge from the negative to the positive region?

2. how much energy is necessary to move to a 1.0 C charge on a 1.0 V equipotential to any other point on that equipotential?

3. A multimeter reads 6.0 V when the probes on are placed at point a and b. Point a near a negative electrode and point b is near a positive electrode. If a 1.0C is moved from a to point b, what happens to its electric potential energy?

Explanation / Answer

1. Work=voltage difference x charge =5x2 J=10J

2. As the point are equipotential no energy is needed to move the charge.

3.potential energy will increase .

Potential energy increase=voltage difference x charge =6 x1 J=6 J
