inductor to resolve the arcing phenomena across the switch. At t 0‚ when the switch is opened‚ the diode is forward bias hence allowing current to its branch. The current‚ I in this circuit is then given by: (VL - VF ) /R ‚ where VF is the forward voltage drop of the diode. The stored energy in the inductor is dissipated as heat in the resistor. Consequently‚ there will be no more arcing or ‘sparks’ across the contacts of the switch. 2. Current that is needed

driven at its resonance frequency. In addition‚ the amplitude I0 of the AC current in a series LRC circuit depends on the amplitude V0 of the applied voltage and the impedance Z‚ which is a measure of the overall opposition of a circuit to the flow of an electrical current as ‚ So we just need to use the apparatus to measure the maximum voltage. As we know‚ at the resonance frequency‚ we have XL=XC and the impedance‚ Z is equal to the resistance R‚ where Z=R. Because the capacitative and inductive

graphite‚ an interference pattern emerges on the screen in front of the gun. The interference pattern shows up as a circle within a circle‚ each of which represents a different interatomic spacing in the graphite lattice structure. As we increase the voltage of the potential difference in intervals of .5kV from 2.5kV to 4.5kV‚ the diameter of the interference pattern will decrease. We did this several times and found that the inter-atomic spacing between the lattice structures of the graphite are 2.51Å

Multiplier type Digital to Analog Converter (MDAC)‚ controlled by a microcontroller‚ serves as the other two arms. The microcontroller‚ after obtaining quadrature condition between the bridge output and one of the designated bridge voltages‚ acquires the current through and voltage across the series connected resistor. With these values and the value of digital input to the MDAC‚ the parameters of L or C or R values are evaluated by the microcontroller and displayed in appropriate display fields. The scheme
