Question

Write on difference between ammeter and voltmeter

Answer 1

Answer:

Explanation:

Voltmeter is an instrument used to measure potential difference (in volt) between two points in an electrical circuit. Ammeter is an instrument used to measure electric current (in ampere) flowing through a cable in an electrical circuit. Internal electrical resistance of a voltmeter should be very high.

Answer 2

Ammeter measures the current flowing through any circuit

Voltmeter measures the potential difference across the circuit

Explanation:

Ammeter :-

• It is a device used to measure the current flowing through any circuit. It is always connected is series as in series current is always same. It have low resistance such that maximum current should flow through it and we get accurate reading. It measures the current in ampere and also have some more ranges like milli ampere, micro ampere etc.

Voltmeter :-

• It is a device used to measure the potential difference across any circuit. It is always connected in parallel as potential is same in parallel combination. It have high value of resistance so that maximum potential drop should be there and we get accurate reading. It measure the potential in volts, milli volts etc.
