Present the relationship between the voltage applied across a conductor and the current flowing through it graphically.

State the relationship between the power P, consumed by a device, its resistance R and current I, flowing through it An electric iron of resistance 20 ohm takes a current of 5A.Calculate its electric power?

Direct current cannot flow through.

State the formula correlating the electric current flowing in a conductor and in voltage applied across it also, show this relationship by drawing a graph. What would be the resistance of a conductor if the current flowing throught it is 0.35 ampere when the potential difference across it is 1.4 volt.

What is the phase relationship between current and voltage in an inductor?

What is the phase relationship between current and voltage in an inductor?
