Under what circumstances does one get an electric shock from an electrical gadget.
How does MCB work
give examples for applications of newton's laws of motion in everyday life.
An electric heater of resistance 8 ohms draws 15A from the service mains 2 hrs. Calculate the rate at which heat is developed in the heater.
The answer given in the NCERT text says 120W but you have calculated it as 1800 J in your NCERT solutions. How and why?
Two fuses of same length are rated 5A and 20A.
Whcih of the fuse wires are thicker and why?
there are other formulae for finding the heat H ? Can you please include the derivations and those formulae also?
pzzzzzz explain ring system of household wiring........ plz it's important......:)
An electric appliance is rated at 1000KVA,220V.If the appliance is operated for 2hrs.Calculate:
(i)kWh
(ii)joule
how does the resistance of a wire depend on its radius?
Difference between Electrical Power and Electrical Energy
please add defination of them, SI and CGS system unit and other info that can help me if this type of question comes in exam
What causes heating effect of current
explain ring system distribution.
does it have any disadvantage?
An electric heater has an operating voltage of 220 V and a power rating of 1000 W. It is connected to a supply of 110 V for 30 minutes.
What is the amount of heat generated by the heater?
A fuse is rated 8A.Can it be used with an electrical appliance of rating 5kW,220V?Why?
A cell of e.m.f 2 volts and internal resistance 1 ohm is connected with two wires of resistances 2 ohm and 3 ohm in parallel. Find the current in each wire.
