We know that,
P = 250 W(Power)
V = 230 V(Voltage)
(i) E = P × t
t = 3600 sec
Given that,
E = 250 × 3600
E = 9 × 105 J
(ii) 1000 Wh = 250 × t
Hence, time,=4 hours
An electric bulb is rated 250 W, 230 V.
(i) the energy consumed in one hour, and
(ii) the time in which the bulb will consume 1.0 kWh energy when connected to 230 V mains?
