Q2. Ohm's law and current
Ans. 
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, given constant resistance.
• Ohm's law equation: V = I * R (voltage = current * resistance)

• Current is the flow of electric charge through a conductor

• Higher voltage leads to higher current flow, given constant resistance

• Lower resistance leads to higher current flow, given constant voltage
