Answer: Option B. ->
False
:
B
:
B
Energy is the ability to do work. Electricity is one of the forms of energy resulting from the flow of electric charges. With the help of electricity, we can do many things like operate machines, light bulbs, fans etc.
Answer: Option A. ->
True

A
Electricity plays a huge part in our every day lives, whether it is at homes or our workplaces.
Our daily routines rely heavily on the use of electricity like using an iron, refrigerator, television, washing machine and so on.
Answer: Option B. ->
two
:
B
There are two terminals in a battery. Battery terminals are the electrical contacts used to connect a load (for example, a bulb) to the battery. Number of terminals in a battery is independent of the number of cells used to make the battery.

Answer: Option D. ->
Air conditioner
:
D
Usually, electric cells/batteries are capable of producing very less amount of electric current. Devices like torch, TV remote, and walkie-talkie require less amount of current to function and the use of electric cell is preferred for these applications.
On the other hand, an air conditioner requires larger current. Air conditioner uses mains power supply for its working.

Answer: Option A. ->
the positive terminal to the negative terminal
:
A
In an electric circuit, the current flows from the positive terminal to the negative terminal of the cell. The image below gives the direction of current, where 'I' denotes the current. The direction of flow of electrons is opposite to the direction of flow of current.

Electrical insulators are materials which do not have free electrons in them and thereby do not allow electric current to flow through them. For example, wood, plastic, etc.
Answer: Option D. ->
Silver
:
D
Silver and copper are good conductors of electricity and allow electricity to pass through them easily. So, we can use silver strip instead of copper strip in a circuit. However, plastic and wood are poor conductors of electricity and do not allow electric current to pass through them easily. Hence, they cannot be used to replace copper.
