Question

Define the electrical circuit.
A. Electrical circuit is a path of electrical components through which the electric current flows.
B. Electrical circuit is a closed path of electrical components through which the electric current flows.
C. Electrical circuit is a combination of components that generate an electromotive force.
D. Electrical circuit is a system that stores electrical energy.

Answer 1

Hint:Electric circuit means a continuous and closed path of electric current. Alessandro Volta develops the first electric circuit. It consists of electrical devices, sources of electricity, and wires connected with a switch's help.

Complete step by step answer:
An electric circuit is a path through which the electric current flows. An electric circuit can also be a closed path in which ends are joined, thereby making it a loop. The electric current flow is possible because of the closed-circuit if the key is opened or disconnected no electric current flows in the circuit. As shown in diagram:
 

Therefore the correct option is (B).

Additional information: It is essential to know about the four basic parts of the electrical circuit. A simple electric circuit consists of a battery, switch, bulb, and resistor.
-Battery: It is used as a source to apply an electric current.
-Switch or key: It is the part of an electric circuit that controls the electric current supply in the circuit. It is used to open or close the circuit.
-Bulb: These are of different types, which can glow when the electric current passes in the circuit.
-Resistor: These are used to reduce current flow or adjust the electrical circuit's voltage.

Note:Electric current and voltage are two basic features of an electric circuit. In Electric circuit analysis in which current and voltage are determined in any element of the electric circuit. There are two types of electric circuits called series and parallel circuits.
