Ohm's Law

If a wall clock is connected to a 9 volt battery that passes a 0.06A current, then what is the resistance (R)?

A. 100 ohms, B. 125 ohms
C. 150 ohms, D. 0.1 ohms
E. 0.125 ohms, F. 0.15 ohms


Answer is C. 150 ohms. To find R: R=V/I. If amp value is mA, ohms result will be kΩ. In this case the amp input it A, thus the result is simply Ω (ohms).
