Priyanka B Solutions for Chapter: Electricity, Exercise 10: Assignment-5

A piece of wire having a resistance $R$ is cut into six equal parts.

If the six parts are placed in parallel, compare the combined resistance with the resistance of the original wire?

How many $330 \mathrm{\Omega }$ resistors in parallel are required to carry $20 \mathrm{A}$ and $220 \mathrm{V}$ line?

Name a component used to regulate current without changing the voltage source. (voltmeter/variable resistor)

A $10 \mathrm{\Omega }$ resistance wire is doubled on it. Calculate the new resistance of the wire.
