Q18: Which part of electric cell or bulb can be connected to form a circuit? Ans: The two terminals-negative and positive.
Which part of the electric cell is connected to a circuit?
between the two terminals of a cell or battery along which an electric current flows, is called a circuit. (2) The positive terminal of the cell is connected to one end of the switch with a piece of copper wire. (3) The other end of switch is connected to one end of bulb holder with another piece of copper wire.
What are the components that can be used to make 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).
How is an electric bulb connected to the cell shown by a diagram?
Explain. An electric bulb is connected to a cell through a switch as shown in Fig. … Show the arrangement of the cells, with a diagram, inside the torch so that the bulb glows. When the chemicals in the electric cell are used up, the electric cell stops producing electricity.
What does a bulb do in a circuit?
A bulb converts electrical energy to light. When electric current flows through it, the bulb produces light. A switch stops and allows the electricity to flow through the circuit.
Is electric a circuit?
electric circuit, path for transmitting electric current. An electric circuit includes a device that gives energy to the charged particles constituting the current, such as a battery or a generator; devices that use current, such as lamps, electric motors, or computers; and the connecting wires or transmission lines.
What are the parts of a lightbulb?
Parts of a light bulb: the glass globe, the metal filament, wires and glass stem, gases and metal base.
- The Globe. ••• The outer glass shell of the light bulb is called the globe. …
- The Filament. ••• …
- Wires and a Stem. ••• …
- Invisible Gases. ••• …
- The Base. ••• …
- Ohm’s Law of Electricity. •••
How does an electric cell produce electricity?
Electric cells produce electricity from chemical reactions inside the cell. Complete step by step answer: Electric cell is an electrochemical device which converts chemical energy into electrical energy. … When we connect these two terminals to an electrical device, electric current or the electrons can flow through it.
Why do the electric cell and the bulb have two terminals?
The bulb glows when there is a flow of charge. The flow will be present only when charges go in and come out as the charges cannot stay inside the bulb. Thus two terminals are present, one for inlet and the other for outlet.
Which circuits will light the bulb?
When the wires in the circuit are connected to the metal casing and metal tip of the bulb, there is a closed (or complete) circuit with the bulb. Electricity will be able to flow through the filament, causing the bulb to light up.
What part of an electric circuit controls the passage of energy?
Electrical energy is energy produced by the movement of certain particles. This flow of particles is called electric current. needs a path along which it can travel. An electric circuit is a pathway through which electric current flows.
What connects the light bulb and the battery?
Light the bulb using two wires. Attach one wire to the negative end of the battery and wrap the other end of the same wire around the base of the bulb. Attach the other wire to the positive end of the battery with electrical tape and to the base of the bulb, completing the circuit and lighting the bulb.
When a fused bulb is connected with a circuit it?
When the terminals of the bulb are connected with that of the electric cell by wires, the current passes through the filament of the bulb. This makes the bulb glow. Sometimes an electric bulb does not glow even if it is connected to the cell. This may happen if the bulb has fused.
How does an electric cell work?
An electrical cell is an “electrical power supply”. It converts stored chemical energy into electrical potential energy, allowing positive charges to flow from the positive terminal to the negative one through an external circuit. … Actually, any charged particle will do the job.
