Question

Name two sources of electricity.

Answer 1

Hint: To answer this question, we need to have the basic understanding of electricity. Electricity is the flow of charges per second through any circuit. Types of electricity are categorized based on the sources used to generate electricity.

Complete step by step answer:
We know that electricity is the flow of charges per second through any circuit. It is mainly of two types: DC current and AC current.
DC current: In which the current is constant with time.
AC Current: In which the magnitude and direction of current changes with time.

Now, to generate electricity there must be a constant voltage drop between the elements and a source of charge which can provide charge to conduct and the energy should be converted from one form to electric energy. These conditions are maintained in a simple electricity generator (like a simple cell). For example a simple dry cell generates in form by converting chemical energy two electrical energy.So, name of two sources of electricity are,
-Dry cell
-Generator and Solar cell

Note: One form of energy is converted to electrical energy by using an electric generator or dynamo. The generator rotates by using some form of mechanical energy, due to this rotation a current is produced in the circuit. Solar cells act in a different manner, they are semiconductor devices. When sunlight falls into the cell a current is generated.
