Is an ammeter is to be used in place of voltmeter the we must connect with the ammeter A?
If an ammeter is to be used in place of a voltmeter, then we must connect with the ammeter a. low resistance in series.
What happens when an ammeter is connected in series with the low resistance in the experiment of measurement of low resistance?
So for correct reading of ammeter should use low resistance. An ammeter is inserted in series with a circuit to measure the amount of current flowing. Its resistance must be low so as to not disturb the circuit. The lower the resistance, the less effect the ammeter has on the circuit.
What happens if ammeter is used as voltmeter?
A voltmeter has high resistance, if connected in series it will increase of circuit and reduce the current in the circuit. When ammeter is connected in parallel to the circuit, net resistance of the circuit decreases. Hence more current is drawn from the battery, which damages the ammeter.
How do you use an ammeter instead of a voltmeter?
In order to use an ammeter in place of voltmeter, you should connect a low resistance in parallel with ammeter in order to reduce the resistance of ammeter device.
What happens when ammeter is connected in series?
A voltmeter has high resistance, if connected in series it will increase of circuit and reduce the current in the circuit. Ammeter aims at measuring the current flowing through the circuit and hence, it is connected in series. Hence more current is drawn from the battery, which damages the ammeter.
Why does an ammeter need to be connected in series?
In order for an ammeter to measure a device’s current, it must be connected in series to that device. This is necessary because objects in series experience the same current. All of the current in this circuit flows through the meter.
What is the resistance of an ideal voltmeter?
infinite
The resistance of an ideal voltmeter should be infinite.
Which instrument is used to measure terminal potential difference as well as EMF?
Voltmeter
Voltmeter is used to measure both terminal potential difference as well as electromotive force (e.m.f.) depending upon the connection state of the battery or cell.
What happens if voltmeter is connected in series?
The voltmeter has a high resistance. When a high resistance voltmeter is connected in series it will not have any current to flow through the circuit. Therefore, a voltmeter connected in series acts more like a resistor and not as a voltmeter.
