Resistors and capacitors are per-haps the most common elements in all electrical circuits. Even if they are not explicitly shown on circuit schematics, they are present in the physical layout, for example, in the form of the unwanted (parasitic) resistance and capacitance of the wiring.
You can reset the capacitor back to a voltage of zero by shorting across its terminals with a piece of wire. The time constant (τ) of a resistor-capacitor circuit is calculated by taking the circuit resistance, R, and multiplying it by the circuit capacitance, C. For a 1 kΩ resistor and a 1000 µF capacitor, the time constant is 1 second.
As presented in Capacitance, the capacitor is an electrical component that stores electric charge, storing energy in an electric field. Figure 10.6.1a 10.6. 1 a shows a simple RC circuit that employs a dc (direct current) voltage source ε ε, a resistor R R, a capacitor C C, and a two-position switch.
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.
Now we will combine the two components together in series form and investigate the effects. Series capacitor circuit: voltage lags current by 0° to 90°. The resistor will offer 5 Ω of resistance to AC current regardless of frequency, while the capacitor will offer 26.5258 Ω of reactance to AC current at 60 Hz.
The time constant of the circuit, defined as τ = RC, is a measure of how long it takes for a capacitor to charge or discharge. In the following exercises, you will investigate time-varying charging and discharging circuits created by placing a resistor and capacitor in series with a power supply.
