JEE Mains · Physics · STD 12 - 3. current electricity
In the given figure \(R_1=10 \Omega, R_2=8 \Omega, R_3=4 \Omega\) and \(R_4=8 \Omega\). Battery is ideal with emf \(12 \mathrm{~V}\). Equivalent resistant of the circuit and current supplied by battery are _______ respectively.
- A \(12 \Omega\) and \(11.4 \mathrm{~A}\)
- B \(10.5 \Omega\) and \(1.14 \mathrm{~A}\)
- C \(10.5 \Omega\) and \(1 \mathrm{~A}\)
- D \(12 \Omega\) and \(1 \mathrm{~A}\)
Answer & Solution
Correct Answer
(D) \(12 \Omega\) and \(1 \mathrm{~A}\)
Step-by-step Solution
Detailed explanation
Here \(R_2, R_3, R_4\) are in parallel \(\frac{1}{\mathrm{R}_{254}}=\frac{1}{\mathrm{R}_2}+\frac{1}{\mathrm{R}_5}+\frac{1}{\mathrm{R}_4}\) \(\mathrm{R}_{254}=2 \Omega\) \(R_{234}\) is in series with \(R_1\) so…
