**Ohm’s Law 3 V is applied across a 6 ohm resistor, what is the current?**

I = 3/6 = 0.5 A For most electronic circuits the ampere is too large and the ohm is too small, so we often measure current in milliamps (mA) and resistance in kilohms (k ). 1 mA = A and 1 k =

Ohm’s Law A lamp connected to a 6 V battery passes a current of 60 mA, what is the lamp's resistance? R = 6/60 = 0.1 k = 100
