Answer 1

Correct answer: circuit 4

Explanation: Electric current is calculated using Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R) (I = V/R). In this case, circuit 4 has the highest voltage and the lowest resistance, so it will have the greatest electric current.
