7. The current and voltage are being measured in the circuit shown below. The two meters nnected correctly and are shown by circles and the resistors by rectangles. Identify are co which meter is measuring what. Meter 2 Meter Meter 1 A. Meter 1 is measuring current B. Meter 1 is measuring voltage C. Meter 2 is measuring current D. Meter 2 is measuring voltage E. Meter 3 is measuring current F. Meter 3 is measuring voltage G. All of these H. Cannot be determined iruit connected to an AC source. If the frequency increases:Explanation / Answer
The meter that is connected in series measures the current while the meter that is connected in parallel measures the voltage.
A Voltmeter has very high resistance to ensure that it's connection do not alter flow of current in the circuit.Now if it is connected in series then no current will be there in the circuit due to it's high resistance. Hence it is connected in parallel to the load across which potential difference is to be measured.
The internal resistance of the ammeter is very low.If we connect it in series, then the maximum current can flow through it. So the accurate current should be measured. If we connect it in parallel then the accurate current can’t be measured
Thus meter 1 and meter 3 are measuring current while meter 2 is measuring voltage.
