In a given circuit, the supplied voltage is 1.5 volts. One resistor is 3 ohms and the other is 2 ohms. Use Ohm's law to determine the current in the circuit.

0.3 amps

1.5 amps

7.5 amps

3.3 amps

You haven't said whether the two resistors are connected

in series or in parallel. It makes a difference.

- - If they are in series, then their combined effective resistance is

(3 + 2) = 5 ohms.

Current in the circuit is (voltage) / (resistance) = 1.5/5 = 0.3 Amp.

- - If they are in parallel, then their combined effective resistance is

(3 x 2) / (3 + 2) = (6/5) = 1.2 ohms.

Current in the circuit is (voltage) / (resistance) = 1.5/1.2 = 1.25 Amp.
