Take Free Practice Test On 2026 JAMB UTME, Post UTME, WAEC SSCE, GCE, NECO SSCE
  • A \(12.0 \mu F\)
  • B \(1.1 \mu F\)
  • C \(1.6 \mu F\)
  • D \(7.7 \mu F\)
Correct Answer: Option B
Explanation:
$$
\frac{1}{R_{\infty}}=\frac{1}{3}+\frac{1}{3}+\frac{1}{4} ; \frac{4+4+3}{12}
$$
$$
\frac{1}{R_{e \Phi}}=\frac{11}{12}, R_{e q}=\frac{12}{11}=1.1 \mu F
$$
