Chapter 22, Problem 43A

To determine

The way in which a voltmeter should be connected in the circuit given in Figure 19 to measure motor’s voltage.

Answer to Problem 43A

Voltmeter should be connected in parallel to the motor.

Explanation of Solution

Introduction:

It is known that the current in series circuit remains same while the voltage remains same in parallel components of the circuit.

Now, to measure the voltage of the motor in the given circuit, the voltmeter should be connected in parallel to the motor as the voltage remains same in parallel combination.

Conclusion:

Hence, the voltmeter must be connected in parallel to the component, potential difference of which is to be determined.
