Homework Statement
sketch the output waveforms when a 5Vp sine wave with a frequency of 100 Hz is applied to each of the following circuits **see attached diagrams**
dancergirlie said:since my zener diode has a threshold of 6.3V, and since my voltage is 5V peak to peak, it will never reach that threshold, so won't it always just be zero output?
Diodes act as one-way valves for electrical current, allowing it to flow in only one direction. This results in a distorted waveform, as the diode blocks the negative half of the alternating current signal.
Yes, a circuit can have multiple diodes which will each affect the waveform in their own way. The resulting waveform will depend on the specific placement and orientation of the diodes in the circuit.
A forward-biased diode allows current to flow through it, while a reverse-biased diode blocks current flow. In a circuit, this results in a different shape of the waveform depending on the biasing of the diode.
The voltage drop across a diode can be calculated using Ohm's law, where the voltage drop (Vd) is equal to the current (I) multiplied by the resistance of the diode (Rd): Vd = I * Rd. The resistance of a diode is typically very small, so the voltage drop is usually negligible.
Yes, diodes can be used in a circuit known as a rectifier to convert alternating current (AC) into direct current (DC). The diodes block the negative half of the AC signal, resulting in a pulsating DC waveform. This can then be smoothed out using capacitors to produce a more constant DC signal.
