\(6 \Omega\) and \(12 \Omega\) resistors are connected in parallel. This combination is connected in series with a \(10 \mathrm{~V}\) battery and \(6 \Omega\) resistor. What is the potential difference between the terminals of the \(12 \Omega\) resistor?
- A \(4 \mathrm{~V}\)
- B \(16 \mathrm{~V}\)
- C \(2 \mathrm{~V}\)
- D \(8 \mathrm{~V}\)
Answer & Solution
Correct Answer
(A) \(4 \mathrm{~V}\)
Step-by-step Solution
Detailed explanation
\(R=\frac{6 \times 12}{6+12}=\frac{6 \times 12}{18}=4 \Omega\) Total resistance, \(R_{\mathrm{eq}}=6+4=10 \Omega\) Current, \(\quad i=\frac{V}{R}=\frac{10}{10}=1 \mathrm{~A}\) The current in \(12 \Omega\) resistor is…
