Q2. How to calculate ESR capacity
Ans. 
ESR capacity can be calculated by measuring the equivalent series resistance (ESR) of a component or circuit.
• ESR capacity is determined by measuring the ESR of the component or circuit.

• ESR is the resistance that exists in series with the ideal capacitance of a component.

• To calculate ESR capacity, use an ESR meter or measure the voltage drop across a known current.

• ESR capacity is important in determining the performance...read more

Q3. What is the peak factor are used for Distribution design
Ans. 
Peak factors are used in distribution design to account for peak loads and ensure safe and efficient operation.
• Peak factors are used to determine the maximum load that a distribution system can handle.

• They take into consideration factors such as diversity of loads, power factor, and future growth.

• For example, a peak factor of 1.5 means that the system should be designed to handle 50% more than the average load.

• Peak fac...read more
