Capacitor Charging and Discharging Part 1 A capacitor charging and discharging phenomenon is one of the most important factor in Analog electronics. There are many electronics circuits in which capacitor charging and discharging plays a very important role. It is also one of the most confusing concept in electronics. In this video we will discuss capacitor charging and discharging phenomenon for four different situation: 1. Time enough to fully charge and fully discharge. 2. Time enough to fully charge but not fully discharge. 3. No time to fully charge but time to fully discharge. 4. No time to fully charge or even fully discharge.      This is a basic R-C series circuit. Circuit consists of a DC voltage source, a capacitor an d a resistor. Now let’s start circuit analysis. It’s a series circuit. So, the common element which is same for all three components is current. Same current is flowing through all the three components....

Half Wave Rectifier Circuit Using Op amp Simulation Using LTspice Definition: The half wave rectifier circuit is a rectifier circuit, which converts an ac voltage to dc voltage. These circuits are called half wave rectifier because it generates output of half cycle for input of full cycle. Another half cycle is wasted. Positive half wave rectifier Input and output waveform of positive half wave rectifier Negative half wave rectifier Input and output waveform of negative half wave rectifier Working principal: For both circuit Vin  is input voltage applied to non inverting terminal of OP AMP. Output is Vout,  feedback to inverting terminal of OP AMP. Open loop output is Vo' . Closed loop connection is formed by connecting a diode (D) between Vo'  and Vout . Voltage drop at diode is  Vd. R is load resistor.  For positive half wave rectifier, when Vin is positive diode is forward biased i.e. diode is on, it closes the feedback loo...

Series Inductor Filter Definition: A filter is a device or process that removes some unwanted components or features from a signal. Rectifier filter is an electronic circuit that removes ripple or unwanted AC signal components from the output of a Rectifier. The main question is, “Why we use inductor filter for rectifier circuit?” The reason is, one of the important property of inductor is, it passes the DC signal but blocks the AC signal. Now what is the meaning of that? The reactance of inductor is 𝑋𝐿=𝑗𝑤𝐿 (𝑤→𝑎𝑛𝑔𝑢𝑙𝑎𝑟 𝑓𝑟𝑒𝑞𝑢𝑒𝑛𝑐𝑦, 𝐿→𝑖𝑛𝑑𝑢𝑐𝑡𝑎𝑛𝑐𝑒 𝑜𝑓 𝑖𝑛𝑑𝑢𝑐𝑡𝑜𝑟). For DC signal, 𝑤=0, so, 𝑋𝐿=0 The output of rectifier circuit (without any Filter) is a pulsating DC. Pulsating DC is a DC signal comprises of unwanted AC component known as ripples. So, if we pass this signal through an inductor, it will able to remove ripples from the output and will smooth the output signal. This the reason we use Inductor Filter for Rectifier circui...
