1.3 Ohm’s law and the power law for a resistor relate V, I, R, and P, making only two variables independent. For each pair identified below, find the other two:
(a)R = 1 kΩ, I = 2mA
(b)V = 1 V, I = 20 mA
(c)V = 1 V, P = 100 mW
(d)I = 0.1 mA, P = 2 mW
(e)R = 1 kΩ, P = 0.1 W
(a) V = 2 V, P = 4 mW; (b) R = 50 k, P = 20 mW; (c) I = 100 mA, R = 10 k; (d) V = 20 V, R = 200 k
