Physics Laboratory, a fluency measure, including fordonsuppgifter how to use the correct resistor color Ahmtr diode: A diode is called the PN bond. If the anode to the cathode is connected to a voltage greater than when it is forward biased and reverse biased reverse. Variety of diodes: 1. Conventional rectifier diodes 2. Zener 3. Light 4. Capacitive 5. Tunnel 6. Optical diode capacitance by changing the voltage across the capacitor changes. Tunnel diode can be reversed to show their strength. A typical diode for rectification or used the wrong polarity protection. Zener diode voltage fordonsuppgifter regulator can be useful. Breakdown voltage zener diodes in addition to their well known numbers. Behavior of a typical diode characteristic curve for this method can be used access points. Zener diode characteristics fordonsuppgifter common to get first test using the access point, and also using the oscilloscope. Diode is a nonlinear device is one-sided. Despite the many changes in the reverse bias voltage fordonsuppgifter does not change much in the opposite direction, the voltage across it does not change much with the change. The anode and cathode of the diode to the way it should be considered. (Characterized by the choice of heads varies) Experiment fordonsuppgifter 1: Evaluation of the half-wave and full-wave rectifier: AC power, ac power supply, but most DC electric appliances are required. (All general IC transistor and the DC power supply is used.) To obtain a proper DC voltage is customary to use the following steps: 1. Convert ac voltage to the required value by a power of 2. Use a mainstream circuit (half-wave or full-wave) (the output of this stage can be used for consumer, non-critical) 3. Use a filter capacitor 4. Regulator fordonsuppgifter or a peak detector is used to adjust the oscilloscope to measure Vm, ac multimeter tester is an effective means to measure Vrms, DC multimeter is an average detector to measure the VDC. It is clear that the DC is a perfect sinusoidal zero. Note that the overall shape of the voltages that we are dealing with a Vm.sin (wt), it is sufficient to calculate the values of Vm by the oscilloscope fordonsuppgifter to measure and put in the appropriate fordonsuppgifter formula. DC and rms values fordonsuppgifter for some typical waveforms: fordonsuppgifter sine full: half sine wave Yksvshdh of the half-wave rectifiers sine wave Yksvshdh all: 1. These circuit packs and see the waveform on the oscilloscope 2. Fill in the table below. (When closing the circuit fordonsuppgifter polarity attention - the use DC coupling - DC voltages with a multimeter and DC voltages with a multimeter ac rms to measure) results: Vrms VDC Vmax trans 13.6 0 3.6 (DIV) * 5 ( Volts / DIV) = 18 (Volts) 7.13 5.7 3.8 Resistance Diode 7.7 5.7 -4.2 * 5 * 5 full-wave rectifier: This waveform can be achieved using trans triceps. It is clear that the DC level of the signal is half-wave mode. The anode and cathode of the diode clamping circuit to ground are considered. (If there is an error burning of diode or transformer) 1. This closed-circuit output voltage with an oscilloscope view and a view of drawing down Vm are. Two. VDC or Vrms measurement of both the President and the relations between them are Czech. fordonsuppgifter (Note that the drop in voltage fordonsuppgifter across the diode is neglected relations fordonsuppgifter with acceptable error would be 2 to 3 volts) results observed on the oscilloscope measurement by multimeter fordonsuppgifter (DC & ac): point ( !) full-wave rms voltage measured with much greater error rate is measured with oscilloscopes, multi-meters. (Value is measured with oscilloscopes is much more accurate) the effect of adding a filter fordonsuppgifter capacitor to the circuit in parallel to the two capacitors are connected to the load. Note that the time constant of the capacitor charging circuit (Τ = RC where R is the resistance of the diode in conduction + resistance wire) is too small, the capacitor is charged by the supplier. But the charging circuit includes a capacitor and a load resistor and capacitor time constant is too large for a considerable time needs to be emptied. If the load resistance of the circuit, we'll see a flat line on the oscilloscope shows the output voltage ripple is affected by the load. (The capacitor can only be unloaded) base-base capacitance is typically shorter base is no longer positive and negative fordonsuppgifter at the same time based on the capacitor body by * Mark this circuit, you will see that Ripple rise time decreases. So by increasing the DC output voltage is reduced slightly. 1. Waveform by the oscilloscope, a DC coupling times, fordonsuppgifter and once we see the ac coupling. Two. The voltage across the load at the ac and DC multimeter would measure and record. Results: Using the output waveform in ac Kvplazhhay DC and the following results were obtained: (a coupling ac, the DC signal is removed and only the DC value is displayed but the ac and ac coupling with the wave DC gathered and full wave form is displayed) with respect to the amount fordonsuppgifter of ripple wave of DC it is too much to see the ripple of ac coupling is clearly necessary.
