The current in the circuit will be decreased by half. Ohm's law states V=IR so, I=V/R. If R is doubled, then I= V/2R.
The current will be halved.
The resistance of a circuit is the total opposition offered to the flow of electric current.
lowers the amt of electrical current flowing through it.
It slows down the current. Resistance has absolutely no effect on the 'speed' of the current. It simply limits its value.
