Q5 of 330 Page 18

Keeping the resistance constant, the potential difference applied across the ends of a component is halved.
By how much does the current change?

As we know that

V = IR

As Current is directly proportional to potential difference

So Current is also become half

Name the physical quantity whose unit is "ohm".

What is the general name of the substances having infinitely high electrical resistance?

State the factors on which the strength of electric current flowing in a given conductor depends.

Which has less electrical resistance: a thin wire or a thick wire (of the same length and same material) ?

Keeping the resistance constant, the potential difference applied across the ends of a component is halved.By how much does the current change?
