Which circuit will have the greatest electric current?

Answer 1

The circuit with the greatest electric current will have the smallest resistance. Looking at the given resistance values, we can see that the resistance of circuit 3 and circuit 4 is smaller than the resistance of circuit 1 and circuit 2. Therefore, the circuit with the greatest electric current is either circuit 3 or circuit 4. Since circuit 4 has a higher voltage value, according to Ohm's Law (V = IR), it will have a greater electric current. Therefore, circuit 4 will have the greatest electric current.
