Question

A circuit has a total resistance of 5 K(omega) and a total voltage of 60V. What is the total current in milliamps?

Answer 1

Assuming your circuit obeys Ohm's law\[V=IR\]Where V = voltage, I = current, R = resistance, your current will be\[\frac{60}{5}mA=12mA\]

Answer 2

what is the power in the circuit in milliWatts?

Answer 3

Power is defined by\[P=IV=I^2R=\frac{V^2}{R}\]for Ohmic circuits so here it is\[12mA \times 60V= 720 mW\]
