1.1 Ohm’s law relates V, I, and R for a resistor. For each of the situations following, find the missing item: (a)R = 1 kΩ, V = 0.5 V (b)V = 2 V, I = 1 mA (c)R = 20 kΩ, I = 0.1 mA (d)R = 100 Ω, V = 5 V Note: Volts, milliamps, and kilohms constitute a consistent set of units. (a) I = 0.5 mA; (b) R = 2 k; (c) V = 2 V; (d) I = 50 mA
