Question

question 8 of 10
which circuit does not allow current to flow through it?
a. circuit d
b. circuit c
c. circuit a
d. circuit b

Explanation:

Step1: Understand current - flow condition

For current to flow in a circuit, there must be a complete closed - loop path.

Step2: Analyze each circuit

Circuit A and C have resistors connected in a closed - loop with a power source. Circuit D has two resistors in a closed - loop with a power source. Circuit B has a break in the loop (open circuit), so no current can flow through it.

Answer:

D. Circuit B
