Calculate the current through a 60 W lamp rated for 250V .If the line voltage falls to 200V, how is the power consumed by the bulb affected ?
A 25W and a 100W bulb are joined in series and connected to the ac mains .Which bulb will glow brighter?
what is the down part of what wwhat is the down part of the switch !!!! pls temme fast
What is denoted by the formula Ti2Ca2Ba2Cu3O10(it is a superconductor)?
why thick wires always carry low current
Why are electrical cables provided with twisted copper wires?
An electric appliance is rated at 1000KVA,220V.If the appliance is operated for 2hrs.Calculate:
(i)kWh
(ii)joule
why are the plugs splitted at their ends?
a wire of 3 ohm resistance and 10 cm lenght is stretched to 30 cm lenght . assuming that it has a uniform cross section , what will be its new resistence?
