question 42

Multiple Choice

A certain galvanometer has a resistance of 100 $\Omega$ and requires 1 mA for full scale deflection.To make this into a voltmeter reading 1 V full scale, connect a resistance of:

• A)1000 \(\Omega\)in parallel
• B)900 \(\Omega\) in series
• C)1000 \(\Omega\)in series
• D)10 \(\Omega\) in parallel
• E)0.1 \(\Omega\) in series
