Question

Resistance is not the only variable that affects the current in an electric circuit. The currentis also affected by the electric potential difference (V) impressed across its ends. The
electric potential difference is simply the battery voltage. As the battery voltage is
increased (by swapping in higher voltage batteries), the current is increased. The
relationship between electric potential difference (V), resistance (R) and current (1) is given
be the equation.
V = IR
This equation, sometimes referred to as the Ohm's law equation. Use this equation to
answer following questions:
A circuit is set up such that it has a current of 8.0 A. What would be the new current if
the resistance (R) is increased by a factor of 2 keeping voltage constant.
the battery voltage (V) is increased by a factor of 3 keeping resistance constant.
the resistance (R) is increased by a factor of 2 and the battery voltage (V) is decreased by a
factor of 2?​
