What do you mean by power rating of an electrical appliance? How to use it to calculate (a) the resistance of the appliance, and (b) the safe limit of current in it, while in use?

What is the difference between charge and energy? Are they interrelated

If a light burns out in a parallel circuit, what happens to other lights that may be connected and why?

Does higher Ohms mean more Resistance?

What factors does the resistance of a conductor depend on?

Define one coulomb charge.

State Ohm's law. Draw a labelled circuit diagram to verify this law in the laboratory. Draw a V-I graph for the same and explain how would you use this graph to determine the resistance of the conductor.

How to find the exact value of ${\displaystyle \csc \left(\frac{5\pi }{6}\right)}$ using the half angle formula?

An electric kettle rated as 1200 W at 220 V and a toaster rated at 1000 W at 220 V are both connected in parallel to a source of 220 V. If the fuse connected to the source blows when the current exceeds 9.0 A, can both appliances be used at the same time ? Illustrate your answer with calculations.
