Two resistors are connected in series across a battery as shown in figure. If a voltmeter of resistance \(2000 \,\Omega\) is used to measure the potential difference across \(500 \,\Omega\) resister, the reading of the voltmeter will be ............... \(V\)
- A \(2\)
- B \(7\)
- C \(8\)
- D \(9\)
Answer & Solution
Correct Answer
(C) \(8\)
Step-by-step Solution
Detailed explanation
\(I=\frac{20}{1000} \,A\) \(V_{1}=I \times 400=\frac{20}{1000} \times 400\) \(=8 \,V\)
