Experiment 2 Resonant circuit - Lab Report Example

However, this current if often affected by several other factors both from within the connection itself and from without i.e. from the external environment. Impedance, the vector sum of reactance and resistance, describes the phase difference and the ratio of amplitudes between sinusoidally varying voltage and sinusoidally varying current at a given frequency. Fourier analysis allows any signal to be constructed from a spectrum of frequencies, whence the circuit's reaction to the various frequencies may be found.

This paper will look at the measurement/ the process of determining the amount of current flowing through an electric circuit by use of a resonator. This is done by analyzing the frequencies of the resonation reflected on the resonator. The level of current transmitted by different sources of power differs depending on the voltage capacity of the source. Sources with higher voltage will result in the increase in the amount of current flowing through the circuit when the loop is closed and the low voltage sources will as well result into low current flowing within the circuit.

When the connection is terminated, the current ceases to flow and the charge stored in the capacitor is lost (as the capacitor discharges) (Hammond). Besides, the resonant is used to establish the amount of charge radiated into the capacitor during charging and the amount/ rate of loss of charges over time as the capacitor discharges. The experiment was carried out by setting up a circuit connection off with an AC power source as the source of current transmitted through the circuit and the two nodes X and Y connected to the resonator.

These nodes reflect the frequency of the current flowing through the circuit as reflected in the wavelengths on the resonator. When the circuit is closed, current flows through it and the wavelengths of the current shown on the resonator, contrary, when the circuit is broken, the current cease to low and the waves ceases to be transmitted across the circuit. This is indicated by the cession in the projection of the waves on the resonator and the cession of the resonation capacity of the resonator.

Certain physical factors are used to determine this variation in the flow of current. These include the amplitude, a, of the waves transmitted through the circuit and the wavelength, ?, of the waves produced as current flows through the connection. While the amplitude of the current shown on the resonator indicates the amount of current passed across at any given instance, the frequency of these wavelengths qualifies the voltage of the power source. The principles mused in this experiment is that of the flow of current in an electric circuit determined by the power source.

That the higher the power voltage, the higher the amount of current flowing through the circuit and vice versa. The capacitance of the capacitors is then determined to indicate the amount of charge stored in the capacitors. This capacitance varies from time to time depending on the voltage strength of the power source. The total capacitance of the device that resonates with the inductance of the winding tested is the distributed capacitance; Cd. Experience shows that this result is considered axiomatic by many Engineers. (Hammond) This experiment id very important for electricians and engineers as it helps them the determine with rather accuracy the
