1.	5. What is short circuit?6. Write two differences between bar magnet and electromagnet.7. Write true or false against the following statements:(1) Combination of two or more cells is called battery.(11) Fuse is a safety device which prevents from electric hazards.(iii) CFL consume more electricity than a bulb.
Answer» Explanation: A short circuit is an electrical circuit that allows a current to travel ALONG an unintended PATH with no or very low electrical impedance. This results in an excessive current flowing through the circuit. The opposite of a short circuit is an "open circuit", which is an infinite RESISTANCE between two nodes. Difference between Permanent Magnet and Electromagnet is magnetic field and STRENGTH. In Electromagnet, the magnetic field is created by a wire-wound coil but the magnetic field of Permanent (Bar) Magnet cannot be changed. True True False

Answer»

Explanation:

A short circuit is an electrical circuit that allows a current to travel ALONG an unintended PATH with no or very low electrical impedance. This results in an excessive current flowing through the circuit. The opposite of a short circuit is an "open circuit", which is an infinite RESISTANCE between two nodes.

Difference between Permanent Magnet and Electromagnet is magnetic field and STRENGTH. In Electromagnet, the magnetic field is created by a wire-wound coil but the magnetic field of Permanent (Bar) Magnet cannot be changed.

True

False
