Question

4. If I_(balb2)=1.5mA and I_(t)=3mA determine I_(motor)

Answer 1

We are given that

and

. We are asked to determine

. We can assume that

represents the total current in the circuit. If the circuit elements (bulb and motor) are in parallel, the total current is the sum of the individual branch currents.Therefore:

We can solve for

:

Therefore, the current through the motor is

.
