Welcome!! Today we are going to show some conversations that give some information on Electricity.
Yes, they are called non - ohmic conductors. They don not obey Ohm's law whereas ohmic conductors do.
WELCOME TO CURRENT ELECTRICITY
Why do they have so many doubts??
Ma'am, yesterday you told about ohm's law and how the current and voltage are related. But i saw that some devices are not following the law.
Fuse is a safety device. It has low melting point and high resistance and is made of alloy.
I didn't learn the fuse part for test. Please help me!!
You know mom, just a few minutes ago, the light was fluctuating and now, no power.. I wonder why that happened!?!
It is because of the varying voltage. Do you know what is voltage? Voltage is the work done per unit charge.
H = I^2*R*tSince heat energy is directly proportional to resistance, the heat energy will increase when resistance will also increase. Understood??
I have a doubt. How will the heat energy change if the resistance is increased??
Hope you gained some information on the chapter Current Electricity!!
