Question # 1
What is short circuit and open circuit mean to you?
- Ans 1: when switched is close and current is passing through the circuit,It is called closed circuit and in this situation resistance is zero whereas the circuit is said to be open if it has infinite resistance and no current is passing through it.

Question # 1
What does the equation H=I2Rt show?
- Ans 1: This equation show the heating effect,During their motion free electrons collide frequently with the atom of metal.on each collision they transfer some of their kinetic energy to the atom with which they collide.And these collisions produce heating effect in the wire.

Question # 1
Why does the resistance of a conductor rise with a temperature?
- Ans 1: As the temperature of the conductor rises,the amplitude of vibration of atoms increase and hence the probability of their collision with free electrons also increases which results in increase of resistance of conductor.
