Q1. Why do we improve power factor.
Ans. 
Improving power factor helps in reducing energy losses, increasing system efficiency, and reducing electricity costs.
• Improving power factor reduces the amount of reactive power flowing in the system, which in turn reduces energy losses.

• Higher power factor means more efficient use of electricity and less strain on the electrical system.

• Improving power factor can lead to reduced electricity costs for consumers and utilit...read more

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)
