Ohm’s Law The electric potential difference V across an ohmic load (resistor) is the product of the current I through the load and the resistance R of the load. V is potential difference in volts, I is current in amps, and R is resistance in ohms. Power Dissipated By A Resistor Power is the rate of work W being done. Remember from unit 1 that change in potential energy
This is called an RC circuit. We start with a circuit composed of an uncharged capacitor, a resistor, a battery, and an open switch, all connected in series. At time initial, ti = 0, we close the switch. We are charging a capacitor through a resistor. Let’s start by adding a loop in the direction of current flow in the circuit.

connected in a circuit only part of the open circuit voltage appears across the external components b. Taking the natural log of the expression for current gives ln(I) = ln(I 0) – kt ln(e), or ln(I/I 0) = –kt k = ln(I/I 0)/t and take a reading from the graph (for example 7.5 A at 0.5 h) gives k = 0.4 hr –1
