How a voltmeter is connected in a circuit
Did you know?
Weba voltmeter is connected across a circuit consisting of a milli-ammeter in series with an unknown resistor R. If the readings on the instruments are 0.5V and 1mA respectively, and if the resistance of the milli-ammeter is 9 ohms, determine; i. the true resistance. WebAn ammeter and a voltmeter are connected in series to a battery with an emf ε = 6. 0 V.When a certain resistance is connected in parallel with the voltmeter, the readings of the latter decrease η = 2. 0 times, whereas the readings of the ammeter increase the same number of times. Find the voltmeter readings after the connection of the resistance.
WebA voltmeter is a high resistance galvanometer used to measure potential difference. A voltmeter is connected in parallel to a circuit element because when connected in parallel it draws least current from the main current. So it measures nearly accurate potential difference. An ideal voltmeter has infinite resistance. WebVoltmeter: A voltmeter (volt + meter) is a device used to measure potential difference between any two points of a circuit.As shown in Fig, a voltmeter is always connected …
