FAQS about Capacitor with resistor

How does a capacitor discharge through a resistor?

Discharging a capacitor through a resistor proceeds in a similar fashion, as Figure illustrates. Initially, the current is I9 − V0 R I 9 − V 0 R, driven by the initial voltage V0 V 0 on the capacitor. As the voltage decreases, the current and hence the rate of discharge decreases, implying another exponential formula for V V.

Why is a capacitor used instead of a resistor?

Capacitor is used instead of an actual resistor to avoid heat loss. 1M resistor is only to discharge capacitor when not under power (safety measure). Your circuit is overly complicated, but in essence to power a led from mains input you need to drop most of the voltage on something that acts like a resistor but does not get hot. thnks for ur info.

How to select balancing resistors for two capacitors in series?

Why is a switched capacitor equiv-Alent to a resistor?

the rate of switching.■ A switched-capacitor circuit is equiv-alent to a resistor only in the sense that their average currents are the same, but not thei

How does a capacitor charge a resistor?

As the capacitor charges the voltage across the resistor drops ( V_R = V - V_"cap") so the current through it drops. This results in a charge curve that starts off at it's maximum charge rate and tails off to a slower and slower charge rate as the capacitor nears its fully charged state.

What is the difference between capacitor voltage and resistor voltage?

So at DC (0 Hz), the capacitor voltage is in phase with the signal voltage while the resistor voltage leads it by 90°. As frequency increases, the capacitor voltage comes to have a 90° lag relative to the signal and the resistor voltage comes to be in-phase with the signal. This section relies on knowledge of e, the natural logarithmic constant.
