Use the information in the table about four different electric circuits to answer the question.
Circuit Resistance (ohms) Voltage (V)
1 0.5 20
2 0.5 40
3 0.25 40
4 0.25 60

circuit 4
Explanation: The electric current in a circuit is calculated using Ohm's Law, which states that current (I) = voltage (V) / resistance (R). In this case, circuit 4 has the lowest resistance and the highest voltage, leading to the greatest electric current.
