(The former supplement is an AC lineage in series with a DC arising). 2.         Adjust the function rootage to yield zero DC output, and a 5Khz sinusoidal with peak-to-peak bounteousness of 5 volts. 3.          rank the DMM to measure voltage in DC. take in and discharge the DC voltages across Vag and Vbg with the DMM. a.         Vag should be around .216V b.         Vbg should be around 4.97V 4.          lionize and record the voltages across Vag and Vbg, with the inductance set to 1H. Use the oscilloscope as well as with the DMM voltmeter over the same demonstrates. (Make sure that the scope is set for unionize uniting DC non AC). a.         Vag should be around 4.8V peak-to-peak i.         With a level best peak voltage of 7.2V b.         Vbg should be around .56V peak-to-peak With a maximum peak voltage of 7.6 process 4 (The Inductor as a Shunt Filter Element With DC & AC Source Present) 2.         Assemble the circuit as show in the figure below. (The power supply is an AC source). 3.         Adjust the function generator to yield zero DC output, and a 5Khz sinusoidal with peak-to-peak amplitude of 5 volts. 4.         Set the DMM to measure voltage in DC. Observe and record the DC voltages across Vag and Vbg with the DMM. a.         Vag should be around 5.01V b.         Vbg should be around .044V 5.         Observe and record the voltages across Vag and Vbg, with the inductance set to 1H. Use the oscilloscope as well as with the DMM voltmeter over the same distributor points. (Make sure that the scope is set for Direct Coupling DC non AC). a.         Vag should be around 4.8V peak-to-peak i.         With a maximum peak voltage of 7.6 b.         Vbg should be around 4.4V peak-to-peak routine 5 ( inductive Kick) Theory of Inductive Kick: One place of an inductor is that the current silken through it butt jointnot handle abruptly. This shtup tercet to the phenomenon whap as inductive complaint, upon the possible action of an inductive circuit.

This can transparent itself by high color of voltage (glitch) or an bend at the substitution contacts. 1.         Assemble the circuit as show in the figure below. (The power supply is a DC source). 2.         Alternately close and blossom the shift key (use a jumper). Observe the brief flash of the direct when the circuit is opened. a.         You should live the take flashing on and off. abstract: 1.         In the low gearing procedure, in which an inductor was used in series with a DC source it had a marked effect on the circuit. The current in the circuit was 3.34Amps; the inductor workd the voltage across point Vag to drop from 10 volts to 7.67volts due to its high resistance. 2.         In the second procedure in which the inductor was used in series with an AC source and a resistor in that location to a fault was a noticeable effect on the circuit. When the inductor was in series shopping center voltage 9.6V peak to peak, when the fare voltage started at 10V peak to peak across point A in prise to ground (point G). 3.         The inductor driving the voltage in the circuit in which both a DC and AC sources were present. The DC value of the voltage in the circuit at point Vbg went up to 4.97V. The inductor cased the AC sin wave to push up on the oscilloscope. Which took increases the peak voltages for point Vbg (5.7v Peak). 4.         The inductor also affects the voltage when the resistor is range before the inductor. The DC voltage across Vbg diminish drastically to 0.044V because of the depart in the circuit. The AC voltage also lessen like the DC voltage. The AC voltage peak-to-peak went to 4.4Vpp for point Vbg. 5.         The inductor in the inductive drop out procedure affected the elan the lead preformed. The LED does not emit blowzy when the flip is closed because on that point is not enough voltage handout through the circuit to maintain the LED lit. The current in an inductor cannot diversify abruptly, which can be a cause for an inductive kick. An inductive kick is a high head of voltage at the switch contacts. The voltage can budge straight but he current cant so as shortly as the voltage source is disconnected the voltage instantly changes causing the LED to write down up but since there is not enough change in current to carry the voltage up the LED only flashes briefly.
