Q5. What is tha current law
Ans. 
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.
• Current (I) = Voltage (V) / Resistance (R)

• It helps in calculating the current flowing through a circuit based on the voltage and resistance values.

• It is represented by the formula I = V/R.

• Ohm's Law is fundamental in understanding and analy
