Why do resistor voltage decrease while capacitor discharges?

The reason why resistor voltage decreases while a capacitor discharges is because the resistor acts like a source of electrical energy. As the capacitor discharges, it draws energy from the resistor, which causes the voltage across the resistor to decrease. This is because the capacitor is acting like a drain, and is taking energy out of the resistor, thus causing the voltage across the resistor to decrease. The resistor and capacitor work together in order to create a discharge circuit. This is done by connecting the capacitor to the resistor, and then to a voltage source. The voltage source supplies the energy to the resistor, and then the resistor transfers this energy to the capacitor. As the capacitor discharges, it takes energy from the resistor, which causes the voltage across the resistor to decrease. In order to understand this process better, it is important to understand the basics of Ohm's Law. Ohm's Law states that the voltage across a resistor is equal to the current through the resistor multiplied by the resistance. As the capacitor discharges, it takes energy from the resistor, which means that the current through the resistor decreases, and therefore the voltage across the resistor will also decrease.

What is RC in electrical?

R for resistor, C for capacitor. RC circuit is a circuit built with a resistor and a capacitor. This circuit will have a typical pulse response that looks like exponential decaying and a typical resonance frequency.


How capacitor used in a timing circuit?

A capacitor relies on the time it takes for the voltage across it to reach a certain value. When it is fully discharged, it acts like a piece of copper wire. ie: it conducts. The voltage across it now is zero. When a voltage is applied to it, it begins to charge, and so the voltage measured across it's terminals increases. This takes time. How much time depends on the voltage applied resistor connected to it and the value of the capacitor.This voltage is then used to energies a relay, turn a transistor on, fire an SCR, and lots of other things.


When is a capacitor like a 0.001 resistor?

A capacitor is like a 0.001 ohm resistor when the capacitive reactance is 0.001 ohms. Capacitive reactance, in ohms, is defined as -1 divided by 2 pi f C, where f is frequency in hertz, C is capacitance in farads, and the -1 means that current leads voltage. Plugging in 60 Hz, and solving for C, you get 2.65 farads. That is a very large capacitor. At 6000 Hz, you get 26.5 millifards, which is still very large. At 6 MHz, you get 26.5 microfards, but at 6 MHz, you need to consider parasitic inductance.

Is mosfet voltage controlled capacitor or inductor?

It's a Field Effect Transistor. I personally wouldn't consider it either of those options; if I had to pick one, it's more inductor-like (in that it has impedance).

What to expect if a resistor is placed in a dc circuit with a capacitor?

when we replace the resistor with a capacitor ,the current will flow until the capacitor charge when capacitor will fully charged there is no current through the circuit because now capacitor will act like an open circuit. for more info plz E-mailt me at "zaib.zafar@yahoo.com"

Explain the function of the capacitor and inductor in a power supply?

A capacitor resists a change in voltage (dv/dt = i/c). An inductor resists a change in current (dl/dt = vl). Together, a capacitor and inductor make a tuned circuit. Usually, in a linear power supply, there is a capacitor in parallel with an inductor in series, and often, in a pi filter, another capacitor in parallel. This reduces the peak to peak voltage at the output. It is also possible to put an inductor in series with the rectifier diode, as as to reduce inrush current. In a switching power supply, things are a little bit different. The primary inductor is a current pump, maintaining constant current flow to the load, controlled by the pulse-width oscillator which switches between on-current from source and off-current from schottky diode. The capacitor in this case filters the output, so as to reduce high frequency harmonics.


What is the meaning of electrical components?

Electronic component are those component which are used to make the electronic circuit it may be active or passive . some active components are - Diode ,FET,BJT,MOSFET, and HEMT etc. while passive component are those device which can not process/amplify signal like- resistor capacitor inductor etc.
