a) name 2 factors on which electrical energy consumed depends?
b) what is meant by power-rating of an appliance? a bulb is rated as 60 W, 220 V. what does it indicate?
c) define electrostatic potential? what is its SI unit?
Pls post each question seperately.
(a)Factors on which electrical energy depend are :
Voltage , current
(b) It means that if a bulb is lighted on a 220 v supply it consumes 60 w electrical power or 60 J of electrical energy converts into heat and light energy in 1 sec.
