Question

A closed path through which electricity flows is called a circuit.
A) True
B) False

Answer 1

Hint: Analyse the importance of circuits for the flow of current. Current flow basically means the flow of electric charges with respect to time. In an electric circuit, when the electric charge is flowing in one direction, the current will flow in the opposite direction.

Complete step by step solution:
Electricity is one of the extremely useful parts of our life. It has become a basic need of our life. For most of the work in our daily life we are completely dependent on electricity. Here we discuss a few ideas about electricity, also about how it works. It is just like the flowing water constitutes water current. In the same way, the flow of charges through a conductor is known as electric current. For the flow of charges some components are needed. If you consider a torch, battery helps for the flow of charges. We have to note that the torch gives light only when the switch is on and also the battery should be placed in proper order. Then, here we can think about the role of the switch. Why will the bulb glow only when the switch is on!

Let us imagine you have to travel from Bengaluru to Mysore to meet your friend. If the roads are blocked in between the cities, you cannot reach Mysore and meet your friend. If the roads are completely free, then only you can meet your friend at Mysore. Now, compare the same example with the flow of charges. There should be a path for the flow of charges. But if the path has broken it will block the flow of charges. To light the bulb, it is mandatory that the charges should flow from source to the bulb. Hence, there should be a complete path for the flow of the charges. In the case of a torch, the switch acts as a gate to allow or to block the flow of charges. A continuous, unbroken path through which electrons can flow is a closed circuit. When the switch is off, it breaks the path to flow the charges. A break or opening in a circuit creates an open circuit. Circuit is defined as the systematic arrangement of cells, wire, electric device and switch through which electric current can flow. When the switch is on, then there will be a closed path for the flow of charges. Hence, we conclude that for the flow of current always a closed path is required which is known as circuit.

Hence, the given statement is True.

Note: For all the types of flow of current always the closed path is required even like small components like torch. In most of these cases switches play an important role.
