Capacitors

Capacitor is a passive component used to store charge. The charge (q) stored in a capacitor is theproduct of its capacitance (C) value and the voltage (V) applied to it. Capacitors offer infinitereactance to zero frequency so they are used for blocking DC components or bypassing the ACsignals. The capacitor undergoes through a recursive cycle of charging and discharging in ACcircuits where the voltage and current across it depends on the RC time constant. For this reason,capacitors are used for smoothing power supply variations. Other uses include, coupling the variousstages of audio system, tuning in radio circuits etc. These are used to store energy like in a cameraflash.

Resistors

Resistor is a passive component used to control current in a circuit. Its resistance is given by the ratioof voltage applied across its terminals to the current passing through it. Thus a particular value of resistor, for fixed voltage, limits the current through it. They are omnipresent in the electroniccircuits.

The different value of resistances are used to limit the currents or get the desired voltage dropaccording to the current-voltage rating of the device to be connected in the circuit. Resistors can beeither fixed or variable. The low power resistors are comparatively smaller in size than high powerresistors. The resistance of a resistor can be estimated by their colour codes or can be measured by amultimeter. There are some non-linear resistors also whose resistance changes with temperature orlight. Negative temperature coefficient (NTC), positive temperature coefficient (PTC) and lightdependent resistor (LDR) are some such resistors. These special resistors are commonly used as

sensors.

6. Result

The circuit is designed for high voltage generation (15-50Kv). The generator ignite voltage spark upto 50 Kv and measured by special custom made probe before displayed the waveform on the

oscilloscope. It act as a standard lightning surge model in the future if the original circuit isconnected to certain specific route. It also will proceed as a tester in the electromagneticcompatibility and applied to the filtering part, where, by using Fourier series, we can develop a filterwhich can eliminate the unwanted frequency in the impulse signal.

7. Applications and Future Aspects

It can be used as high voltage generator (15-50kV).

With a little modification, this simple project can be converted into a plasma generator.

Very usefull in that areas where power generation is low

Used as a security project also.

Used as an electronic bomb.

8.Limitations.

Output signal of the ignition coil is unknown

Relatively small amplitude with a high frequency
