Question
Download Solution PDFTwo voltmeters have the same range of 0-400 V and have an internal impedance of 30,000 ohms and 20,000 ohms respectively. If they are connected in series and 600 V is applied across the series circuit, the voltmeter readings are
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFVoltage division Rule:
\(V_{th}=V_s\times {R_{th}\over R_1+R_2...R_{th}}\)
The voltage across the first voltmeter \({V_1} = 600 \times \left( {\frac{{30000}}{{50000}}} \right) = 360\;V\)
The voltage across the second voltmeter \({V_2} = 600 \times \left( {\frac{{20000}}{{50000}}} \right) = 240\;V\)
