Write the formula for electric power in terms of potential difference and current.
Two lamps, one rated 220 V, 50 W and the other rated 220 V, 100 W, are connected in serieswith mains of 220 V. Explain why does the 50 W lamp consume more power
An electric bulb is rated 250 W, 230 V. Calculate:
- the energy consumed in one hour
- the time in which the bulb will consume 1.0 kWh energy when connected to 230 V mains.
What is the order of current drawn by appliances connected to the ‘light circuit’ of a household?
What is the order of current drawn by appliances connected to the ‘power circuit’ of a household?
Establish the relation that heat produced in a metallic conductor due to the flow of current is V2t/R joules, where V is the potential difference across the ends of the conductor, R its resistance and t is the time in second for which current flows.
Find the heat produced in joules when a current of 10 amperes flows through a connecting wire of resistance 2 × 10-2 ohms and heating element of resistance 250 ohms for 2 seconds.
An Electric bulb is marked 100 W, 230 V. What how long would this lamp take to consume one unit of electricity?
A electric bulb is rate 220 V, 60 W. its electric cell resistance is nearly
