Answer 1

$\large\mathbf{QUESTION}$

What is electric current?

$\huge\underline\bold\pink{Answer}$

An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume.

$\large\mathbf{QUESTION}$

Mention the use of battery in an electric circuit

$\huge\underline\bold\pink{Answer}$

A battery is a device consisting of one or more electrochemical cells with external connections for powering electrical devices such as flashlights, mobile phones, and electric cars. When a battery is supplying electric power, its positive terminal is the cathode and its negative terminal is the anode.

$\large\mathbf{QUESTION}$

Write

the factors on which the resistance of a conductor depends.

$\huge\underline\bold\pink{Answer}$

The resistance of a conductor depends on the cross sectional area of the conductor, the length of the conductor, and its resistivity. It is important to note that electrical conductivity and resistivity are inversely proportional, meaning that the more conductive something is the less resistive it is.

Answer 2

Answer:

Hope it was helpful

Explanation:

The flow of electrons in a direction is called electric current . Battery is used in circuit because it converts chemical energy into electric energy. The factors on which resistance depends upon are

1)The temperature of the conductor

2)The cross-sectional area of the conductor

3) Length of the conductor

4)Nature of the material of the conductor
