The circuit below shows some of the circuitry in a small toy robot. When the circuit is on, the robot moves its arms (the motor) and blinks a light on its head (the light bulb). 9v battery
18 ohms motor
18 ohms light

A. How much current is in the circuit when these things are happening? Hint: To find the total resistance of the circuit, add the two resistances together.
