Question. No: 1

A light bulb is connected to a 260V potential, and produces 120-Watts of light and heat. What is the resistance of the wire in the light bulb?

Question. No: 2

Current decreases when passing through a resistor and then increases again upon exiting. Is it true or wrong explain in each case.

Question. No: 3

A person walks by. And the person contains electrons. Therefore, there is a presence of current. Either yes or no justify this statement with reason.

Question. No: 4

Select one the most closely related choice given below and write the reason of your selected choice as well.

a) Electrons from the sphere will be attracted to the balloon and leap from the sphere to the balloon

b) Protons from the sphere will be attracted to the balloon and leap from the sphere to the balloon

c) The balloon will attract electrons in the sphere and repeal protons in the sphere, so the net force on the sphere is zero

d) The balloon will attract electrons in the sphere and attract protons in the sphere, so the net force on the sphere is zero

e) The balloon will cause a polarization of charge in the sphere

Question. No: 5
