Q1. Om law in v=I×R
Ans. 
Ohm's Law states that the voltage (V) in a circuit is equal to the current (I) multiplied by the resistance (R).
• V = I * R

• Voltage is measured in volts (V)

• Current is measured in amperes (A)

• Resistance is measured in ohms (Ω)

• Example: If a circuit has a current of 2A flowing through a resistance of 5Ω, the voltage would be 10V (2A * 5Ω = 10V)

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
