Answer:
1.A primary cell is used once & then discarded, it cannot be reused after charging in electricity !
2.If a substance is conductor then it will get attracted toward the electricity! Conductor can make a closed circuit if we joint it with a circuit.
3.A circuit has mainly the following parts
i. A cell/battery
ii.A switch
iii.Current carrying wire by which we can make a whole circuit obviously!
iv. Resistance
v.Bulb or any appliances
4.Electric switch works by the following process
i. when we press the ON button of a particular switch the current started following in the whole circuit.
ii. If we pressed the OFF button of switch then current stopped flowing in the circuit & hence, circuit stops working.
HOPE IT HELPS!!!!

explained ahead:-
Explanation:
1)A primary cell is a battery that is made to be used one time only. It cannot be recharged. Once all the power is used up, the battery must be thrown away. It no longer makes electricity. Primary cells are often used to give power to small appliances that are used in the home.
3)The Basic Parts of an Electric Circuit
Every electric circuit, regardless of where it is or how large or small it is, has four basic parts: an energy source (AC or DC), a conductor (wire), an electrical load (device), and at least one controller (switch).
Visualize what happens when you switch on a room light. You toggle or push a switch to "turn on" the light. Your action causes electricity to flow (much like water flows through a pipe) through the wires of the electrical system to the bulb, which converts the electrical energy traveling through the wires to visible light. The process is essentially the same for powering up a computer, or turning on a TV, or providing the electrical power needed to start or operate any electrical device.
4)An electric switch is a device that interrupts the electron flow in a circuit. Switches are primarily binary devices: either fully on or off and light switches have a simple design. When the switch is turned off, the circuit breaks and the power flow is interrupted. Circuits consist of a source of power and load. A load is a power-powered device. The function of an electric switch is to regulate the current between the load and source of power. The power source is the electrons that push through the circuits. The voltage is the quantity of force or pressure applied by the power source. Power sources must have a negative and positive endpoint. The negative terminal connects to the charge, and the electrons drive through the circuit. The load receives the current and returns it via the positive terminal to the power source. The electrical switch is inserted in this loop.
Electrical switches work according to a basic design. The most common switches are the on/off toggle ones. Three-way and dimmer circuits are similar in design. Three-way circuits consist of two separate switches that control the same device, while a dimmer circuit controls only the amount of electricity that passes. Electric circuits work when electricity can move in a continuous loop. The electricity cuts off once the circle is broken. This is where the switch comes in. A toggle on/off circuit breaks the current when it is off. The current or loop completes itself when it’s in ” on ” position.
