question 8 of 10\nwhich circuit does not allow current to flow through it?\na. circuit d\nb. circuit c\nc. circuit a\nd. circuit b
Answer
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
