physics

A 10-volt power supply is used to power a circuit, producing a current of 2 A. If the total resistance of the circuit is doubled, how will this affect the circuit?

The current will change so that the voltage drop for a complete loop through the circuit becomes 5 V.

The voltage drops across each resistor will be unaffected because each will remain at 0 V.

The current will change so that the voltage drop for a complete loop through the circuit remains at 10 V.

The voltage drops across each resistor will all double to match the change in resistance.

  1. increasing the resistance lowers the current

    the supply voltage doesn't change
