Which makes the conducting link between the cell and the bulb in the torch?

The conducting link between the cell and the bulb in a torch is the wires inside the circuit. When the switch is turned on, the circuit is completed, allowing the electrical current to flow from the cell through the wires and to the bulb, causing it to light up.


What materials are conductors in a torch?

The conducting path of a torch is a simple circuit: Battery to switch, switch to bulb, bulb back to battery. Provided the switch is on, and there are no breaks in the circuit wiring (and the bulb is good), the torch should work.


What 6 things do you need to make a torch?

to make a torch you need batteries (obviously), a switch (you can buy a standard switch or make a pressure switch out of foil and cardboard), a light bulb, wires (3 if you are using any kind of switch) and a housing (something to hold the batteries, wires, light bulb etc. together). I would also recommend using a light bulb holder and wires with alligator clips (if you dont have solder) as these make the construction more sturdy. they may increase bulk but they are worth it especially as it is easy to replace the bulb and there is no solder needed therefore nothing has to be broken to replace anything.


What is inside a torch?

Inside a torch ther is a bulb a cell and a swith. with some wires connecting them. it is a simple series circuit.


Define the parts of the electric circuit?

The parts in an electric circuit are as follows: wires that contain two D-cells, a light bulb, and a switch, the D-cells are the energy source, the bulb is the load, the switch controls the flow of electric charges and the connecting wires provide a complete path that joins all the parts together.


What is an electric torch?

A torch consist of a plastic casing,a bulb ,electric cells. a slide switch and a reflector. Firstly complete the circuit and then put two electric cells or batteries into the plastic case.when you close the switch the circuit will be complete and the bulb will glow. The reflector will pass the light too the big distance and and lighten the distance upto where the light the goes.


How a torch works?

A torch has six main parts. The bulb, the switch, the batteries, the wiring, the reflector, and the case. The switch connects the batteries to the bulb via the wiring. The reflector focuses the lamp beam, and the case holds all of the parts together.


How does a torch work-circuit'?

A torch is simply a circuit containing a battery, a bulb and a switch. The three components are connected in series (one after the other) to form a loop. The switch simply completes the circuit so that power flows from the battery to the bulb.

What does the switch do in a torch?

The switch in a torch controls the flow of electricity to the light bulb. When the switch is turned on, it completes the circuit and allows the electricity to pass through, lighting up the bulb. Turning the switch off breaks the circuit, stopping the flow of electricity and turning off the light.


Why does the bulb not light until you press the switch?

there is no electricity running thru the wires yet
