Question

state ohms law
what is reostate

Answer 1

According to ohm's law the current flowing through the conductor is directly proportional to the potential difference across it ends provided the physical conditions and temperature of the conductor is constant.

Rheostat
AN electrical instrument used to control a current by varying the resistance is called rheostat.

Hope this helps u!


All the best for ur xam ☺☺

Answer 2

at a constant temperature the current passing through a conductor is directly proportional to the potential difference acriss tow ends.
reostate- it is a device used to change the current in a circuit with our changing the voltage source.
