Welcome to Pakistan Science Club
Here we are with a new project
and that is
Simple wireless electricity transmission
we will make it by using very simple components
The things we require are
Scotch tape either 1 cm width or wider
copper wire of gauge 26-28
a capacitor of 3000 micro farad
3 silicon diodes
two resistors of 3.3 kilo ohms
The important component is a transistor
its number is TTC5200
and a small bulb
First we will take scotch tape or paper tape roll whose diameter is about 8 cm and make a coil on it
Here we have one coil ready
we have made 3 terminals of the coil
2 terminals are of single wire and the central one is of double wire
we have made the coil of 50 turns
we will connect all the components according to the circuit diagram
Here if we observe transistor according to our diagram
The leftmost is Base terminal of transistor
The central terminal is collector
and the last on the right is Emitter of the transistor
we will now connect our coil according to this
one end of the coil is connected to the resistors
either you can use one resistor of 6.6 kilo ohms or 2 resistors of 3.3 kilo ohms can be used in series
Before connecting the resistor, we will remove insulation coating of copper wire
Here we are connecting one resistor with it
and the second terminal of the resistor is connected to the base terminal of the transistor
Now we will connect the second terminal of the coil according to diagram
we have connected our first terminal
It can be seen that there are two resistors in circuit diagram that are of 3.3 kilo ohms
but here we have used one resistor of 6.6 kilo ohms
the third terminal of coil is connected to the central terminal of transistor i.e. collector
Here we have completed our primary coil
Now we will make secondary coil
for secondary you will use same diameter object
and make a coil of approximately 20-30 turns
Here we made this one
Now our system is ready for testing
We are connecting a wire at the Emitter of the transistor
Remember that central terminal of the primary coil will be connected to the positive terminal of power source
and the emitter of the transistor that is at the rightmost will be connected to the negative of power source
now we are connecting our power source i.e. 12 volts
Here you can see as we completed the circuit, the LED start glowing
Our transistor is heating up so we will use a heat sink
we will join the transistor with heat sink to absorb its excess heat
Now we will test it by keeping it vertical
and measure how far it is transmitting electricity
Approximately at a distance of 15 cm, the LED is glowing
Now we are testing a tungsten filament bulb that is of 6 volt and 2 watts
you can see that the bulb is also glowing
We have completed our project and will perform 2 different test on it
we have seen that our tungsten bulb was also glowing
First here we have made a very small coil with LED
now we have connected a diode, a capacitor and a PC fan with our secondary coil
Lets check whether it works or not
Good..!! its working
