Question

Use the information in the table about four different electric circuits to answer the question.

Electric Circuit Characteristics
Circuit Resistance (ohms) Voltage (V)
1 0.5 20
2 0.5 40
3 0.25 40
4 0.25 60
Which circuit will have the greatest electric current?

(1 point)

circuit 1

circuit 3

circuit 4

circuit 2

Answer 1

Circuit 4.

Compute I = V/R:
- Circuit 1: 20 / 0.5 = 40 A
- Circuit 2: 40 / 0.5 = 80 A
- Circuit 3: 40 / 0.25 = 160 A
- Circuit 4: 60 / 0.25 = 240 A

Circuit 4 has the greatest current.
