Q1: An equivalent circuit is one that produces the same voltage and current to a given load as the original circuit that it replaces.

ANS:A - True

Dear Sir,

Energy flow is constraint of time factor, and difference in low resistance, energy can saved application of standard wire and not non quality wires because of high resistance values, but obviously energy savings are getting in high and non quality wire.

No doubt low resistance, high current capacity: Energy high reading.

High resistance, low current capacity: Low readings.

How can I explain to customer, to use low and specified resistance values?

Can we explain P = Square times of Voltage/Resistance formula.

I shall be grateful, if we can through, if can explain, how can we explain to save by keeping low resistance values of wires?
