How do you calculate the reading on an ammeter?

How do you calculate the reading on an ammeter?

V=IR, here V is the potential difference across a resistance R through which a current I is flowing. The ammeter is connected in series with the circuit. So its reading will show the value of the current flowing in the circuit. Hence, the reading of the ammeter is equal to 1A.

What reading does the ammeter show?

Ammeter in Series: An ammeter (A) is placed in series to measure current. All of the current in this circuit flows through the meter. The ammeter would have the same reading if located between points d and e or between points f and a, as it does in the position shown.

What is the indication of the ammeter a2?

An ammeter measures the current flowing through it. The unit of current is Amps. Amps is abbreviated as A. So 2A means 2 Amps of current is flowing through the ammeter, which also flows through the resistor and the battery as they are all in series.

What is ammeter Class 10?

An ammeter is a device (instrument) used for measuring large electric currents in ‘ circuits. For this purpose, it is put in series with the circuit in which the current is to be measured.

What is the reading in ammeter a2 and a3?

Reading in Ammeter A2 is 1.6 A. A3 = A1 + A2 = 2.4 + 1.6 = 4.0 A.

What is ammeter Class 10 CBSE?

Ammeter (ampere meter) An ammeter is a device (instrument) used for measuring large electric currents in ‘ circuits. For this purpose, it is put in series with the circuit in which the current is to be measured.

What is the reading of ammeter and voltmeter class 10?

Hence, the readings in the ammeter and voltmeter are 0.24 A and 2.88 V.

What is voltmeter ammeter method?

The magnitude of resistance can be measured by different methods. One method is to measure the voltage drop V across a resistance n a circuit with a voltmeter and the current I through the resistance with an ammeter. Then using Ohm’s Law, R = V/I.
