The current in a certain resistor is 0.60 a when it is connected to a potential difference of 373 v. what is the current in this same resistor if the operating potential difference is 139 v? answer in units of a.

As we know that resistance of the resistor will remain same while connecting across different batteries

So here we will say by ohm's law

here we know that

now we have

now we have

another voltage as V = 139 volts

now we have current

so final current is 0.22 A

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

wire in brush may conduct electricity from cell to drill and vice versa electrc shock possible
