(a)Name a device which helps to maintain a potential difference across the
ends of a conductor,
(b)What is meant by saying that the potential difference between two points
is 1 V?
(c)Define Ohm's law. Write an expression for it.
(d)What is the unit of resistance?
(e)When the potential difference between the terminals of an electric heater
is 110 V, a current of 5 A flows through it. What current will flow through
the heater if the potential difference is increased to 220 V? What is the
resistance of heater?
