Question

question 2 of 10
which circuit does not allow current to flow through it?
a. circuit c
b. circuit d
c. circuit a
d. circuit b

Explanation:

Step1: Recall the condition for current flow

Current flows in a closed - loop circuit. A circuit must have a complete path (power source, conducting wires, and components connected properly) for current to flow.

Step2: Analyze each circuit

• Circuit A: There is a break in the circuit (open - circuit), so current cannot flow.
• Circuit B: It is a short - circuit (no components, but still a closed path in terms of wire connection, theoretically current can flow in a very dangerous way).
• Circuit C: It is a closed - loop with resistors, so current can flow.
• Circuit D: It is a closed - loop with resistors, so current can flow.

Answer:

C. Circuit A
