Tau, symbol τ, is the greek letter used in electrical and electronic calculations to represent the time constant of a circuit as a function of time. But what do we mean by a circuits time constant and transient response. Both electrical and electronic circuits may not always...
For a passive RC integrator circuit, the input is connected to a resistance while the output voltage is taken from across a capacitor being the exact opposite to the RC Differentiator Circuit. The capacitor charges up when the input is high and discharges when the input is low. I...
For a passive RC differentiator circuit, the input is connected to a capacitor while the output voltage is taken from across a resistance being the exact opposite to the RC Integrator Circuit. A passive RC differentiator is nothing more than a capacitance in series with a resist...
RC circuits have the ability to produce different output shapes of RC waveforms depending on the type and frequency (period) of signal waveform applied to its input terminals. In the previous RC Charging and Discharging tutorials, we saw how a capacitor has the ability to both c...
RC discharging circuits use the inherent RC time constant of the resisot-capacitor combination to discharge a cpacitor at an exponential rate of decay. In the previous RC Charging Circuit tutorial, we saw how a Capacitor charges up through a resistor until it reaches an amount o...
The charging of a capacitor is not instant as capacitors have i-v characteristics which depend on time and if a circuit contains both a resistor (R) and a capacitor (C) it will form an RC charging circuit with characteristics that change exponentially over time. All Electrical o...
