what can i use as a load in an electrical circuit oter than a bulb?

Question

i have a project on electrical circuit and i want it to be simple and exclusive

i got a answer to use a electric powered fountain and a buzzer . how do you make theese? i really liked the idea.
I am a 9th std. student and i want to make a simple circuit. for making it presentable i want to use a nice load.

Answer 1

use a ballast resistor.

Answer 2

Just remember a bulb is a variable load. High current to start, lower current when it warms up.

If you want a steady load, and since you said electrical and not electronic circuit, a resistor is a tough one. Finding a large power resistor is difficult and still dangerous.

Loads that don't change cannot have motors, heating elements, tubes, etc. that vary with time. But, if you can live through the start up changes in current, then lights and other devices without thermostats or timers might do the trick- after a few minutes of warm up. One guy suggested making an electro magnet, but you have to be careful and not let the magnetic field change, as in anything metallic getting near it, or that will vary.

Not dealing with the electrical side of things myself, but the electronic, I bet some electrician has a steady resistive load he uses to do these things.

Answer 3

You have either tripped a switch aka breaker or blown a fuse. If it's a breaker you just have to look and see which one is in the off position, which is down rather than up. Once you have replaced the bad bulb just lift the down breaker, it should work ok . Fuses just need checking or replacing if you're not sure if one has blown. If your fuse board is not labelled, then take the trouble to find out which fuse/breaker supplies which circuit, and label them all clearly. This will save a lot of stress in the long term. Keep a torch near the fusboard so you can see the fuse board when the lights don't work.

Answer 4

I don't know how much power is needed for your project.
I used to use nicrome wire as a load. If you want the variable load then use rheostat. Or you can make an active load which involve some electronics. Active load is capable of changing the amount of load very smoothly.If you are interested I can give you a circuit diagram to make yourself.

Answer 5

A resistor can be used to create only heat.
A motor for creating mechanical energy
A speaker or buzzer for creating sound (speakers will only click as you apply or remove the power since they are AC devices).
An LED is like a bulb, but it's solid state (you must use a resistor in series to prevent the LED from burning out).

Answer 6

Anything really ..... a buzzer; a motor; a relay; a small transistor radio .....

But if you want to do something really impressive, wind yourself an electromagnet. You will need several metres of thin wire (no thicker than 22 SWG). If you wind it directly onto a steel core (such as a 15cm. nail or coach bolt) it should easily be able to pick up paper clips, steel dressmaking pins or small screws, or attract a piece of steel plate attached to something else towards itself. If you wind it onto a cardboard or plastic tube, it should be able to attract a steel nail right into the tube when powered up.

I'm sure you can think of plenty of uses for that!

Answer 7

try attaching it to an electrical powered fountain. that way, if your circuit is good, the fountain will erupt.

Answer 8

One has to be more specific. What is the voltage? the power ? What is the power of the lamp that is intended to be replaced? etc etc. One can expect extremely helpful answers if questions are explicit.

Answer 9

Any non inductive resistance of the right value.
