JEE Mains · Physics · STD 12 - 3. current electricity
In the figure shown, the current in the \(10\, V\) battery is close to
- A \(0.36 \,A\) from negative to positive terminal.
- B \(0.71\, A\) from positive to negative terminal.
- C \(0.21\, A\) from positive to negative terminal.
- D \(0.42\, A\) from positive to negative terminal.
Answer & Solution
Correct Answer
(C) \(0.21\, A\) from positive to negative terminal.
Step-by-step Solution
Detailed explanation
\(E _{ eq }=\frac{20 \times 10}{17}=\frac{200}{17}\) and \(R _{ eq }=\frac{7 \times 10}{17}=\frac{70}{17}\) \(\therefore \quad I=\frac{\frac{20}{17}-10}{4+\frac{70}{17}}=0.21 A\) from \(+ve\) to \(-ve\) terminal
