Problem: A 9.0-V battery is connected to a resistor so that there is a 0.50-A current through the resistor.For how long should the battery be connected in order to do 320 J of work while separating charges?

FREE Expert Solution

Ohm's law:

i=VR, where i is current, V is voltage, and R is resistance.

From work-energy principle, work:

W=Pt, where P is power and t is time.

Power:

P=i2R
