Question

In a given circuit, the supplied voltage is 1.5 volts, and the resistor value is 3 ohms. Use Ohm's law to determine the current in the circuit.

2.0 amps
0.5 amps
4.5 amps
1.5 amps

Answer 1

0.5

Step-by-step explanation:

Answer 2

Current in the circuit =

(supplied voltage)
divided by
(the net effective resistance of everything in the circuit) .

If the 3-ohm resistor is the only thing in the circuit, then

Current = (1.5 volts) / (3 ohms) = 0.5 Ampere .
