1. Calculate the resistance of a bulb, if the current is 0.5A and the Voltage across the bulds is 2V.

2. Calculate the Voltage across a bulb if the resistance of the bulb is 3 and the Current flowing is 2 A.

3. Calculate the Current flowing through a wire if the battery is 10volt battery and the wire has a resistance of 2 ohms

4. What is the Voltage required to create a 20 amp current if the resistance of 4 ohms
