Directions (Q.8 to Q.10) : Read the following paragraph and answer the questions given below.

Resistance is not the only variable that affects the current in an electric circuit. The current is 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 (I) is given be the equation. V = IRThisequation, 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

8.the resistance (R)is increased by a factor of 2 keeping voltage constant.

9.the battery voltage (V) is increased by a factor of 3 keeping resistance constant.

10.the resistance (R) is increased by a factor of 2 and the battery voltage (V) is decreased by a factor of 2?
