Answer 1

Required answer:

We know that electricity plays a very vital role in our lives. It is very difficult to imagine a world without electricity. Each day we use electricity in a countless number of ways without giving it much thought.

Electric Current :

You already know that electricity is the movement of charges through a body and the flow of electric charges is called current. All materials do not allow current to flow through them. Keeping this in mind, materials are categorised as conductors and insulators.

Terms You Should Know !

• Electrodes : Electrodes are the two terminals through which an electric current enters or leaves a battery.
• Electrolyte : Electrolyte is a liquid that allows electric current to paßs through it.
• Anode : The positive electrode where the negative ions collect is known as anode.
• Cathode : The negative electrode where the positive icon collect is known as cathode.
• Ionisation : Ionisation is the process of formation of ions.

Points related to electric currents :)

Electric charge is an inherent property of matter most object have any quantity of positive and negative charge they are electrically neutral when the balance is disturbed, in a charge is left on the object and the study of charge is called electrostatics.

In some material known as electric conductors they are electrons free to move about in this the presence of an electric field produces a steady flow of charge in the direction of the field such a flow constitutes an electric currents measured in amperes. Material which high resistance to current are called insulators. Electric charges flow in the form of electrons electrons flow from negative terminal into the wire then enters the positive terminal.

Electric sources such as batteries or generator is converted Chemicals magnets or other energy into electrical energy batteries create a constant voltage and so produce a steady or direct current many generator on the other hand provide a voltage with changes in value and direction many times a second and changes in value and direction many times a second and so produce alternating currents in which charges move to and fro instead of flowing continuously in one Direction this system has advantage in generation transmission and application and is now used mostly universally for domestic and industrial purposes.
