Question

Help me in answering please

Answer 1

Answer:

14 . the other name of variable resistance is rheostat.

Explanation:

15.An ammeter is connected in series with the circuit to be measured. The ideal ammeter will have zero resistance so as not to disturb the circuit.

16.the unit of electric resistance that is volt per ampere is called ohm.

HOPE IT HELPS ☺

Answer 2

Answer:

13)Ammeter is used to measure the strength of current in an electric circuit, it is always connected in series with a circuit, hence its introduction should not change the current, so it has low resistance.

14)The another name for variable resistance is rheostat.

15)An ammeter is connected in series with the circuit to be measured. The ideal ammeter will have zero resistance so as not to disturb the circuit. We will find the shunt as part of the ammeter circuit.

16)SI Unit of Resistance

There is something called specific resistance or resistivity which is measured by the unit ohm-meter or ohm-m.
