P = I^{2}R

Where P = power

I = Current

R = Resistance

Description : What is the mathematical relationship between resistance and conductance?

Description : What is the relationship between power and current?

Answer : P = I2R Where P = power I = Current R = Resistance This the relationship between current and power.

Description : In a transformer the resistance between its primary and secondary should be?

Answer : In a transformer the resistance between its primary and secondary should be infinity.

Description : When an alternating current passes through an ohmic resistance the electrical power converted into heat is?

Answer : When an alternating current passes through an ohmic resistance the electrical power converted into heat is true power.

Answer : The inductive interference between power and communication line can be minimized by transposition of the power line, transposition of the communication line.
