AI Customer ServiceThe capacitor reacts very differently at the two different frequencies, and in exactly the opposite way an inductor reacts. At the higher frequency, its reactance is small and the current is large.
AI Customer ServiceWith AC, there is no time for the current to become extremely large. Consider the capacitor connected directly to an AC voltage source as shown in Figure. The resistance of a circuit like this can be made so small that it has a negligible effect compared with the capacitor, and so we can assume negligible resistance.
Capacitive reactance can be thought of as a variable resistance inside a capacitor being controlled by the applied frequency. Unlike resistance which is not dependent on frequency, in an AC circuit reactance is affected by supply frequency and behaves in a similar manner to resistance, both being measured in Ohms.
Both capacitors and resistors are important components in circuits, especially delay or timer circuits. Combining resistors and capacitors in a circuit will increase / decrease a timing sequence. A simple circuit is shown shows four capacitors and resistors in parallel.
Unlike the resistor which dissipates energy, ideal capacitors and inductors store energy rather than dissipating it. In both digital and analog electronic circuits a capacitor is a fundamental element. It enables the filtering of signals and it provides a fundamental memory element.
Combining resistors and capacitors in a circuit will increase / decrease a timing sequence. A simple circuit is shown shows four capacitors and resistors in parallel. On the left hand side of the circuit an LED is seen, this is protected by a 300 ohm resistor.
Unlike resistance which has a fixed value, for example, 100Ω, 1kΩ, 10kΩ etc, (this is because resistance obeys Ohms Law), Capacitive Reactance varies with the applied frequency so any variation in supply frequency will have a big effect on the capacitor’s, “capacitive reactance” value.
