Capacitors are one of the most common electronic components that have a high proportion of products. With the development of the information age, more and more electronic products appear around us, which also drives the growth of the capacitor industry. Now we come to understand how to calculate the resistance of a capacitor, let's take a look. The two plates of the capacitor are not insulated and have a relatively large equivalent resistance. Therefore, even if the capacitor is full of charge, even if the external resistor is not connected, it will be discharged naturally through its own large resistor after a long time. The resistance of the capacitor in the AC circuit is called the capacitive reactance mode, called Xc, the calculation formula is Xcu003d1/(ωC)u003d1/(2πfC), f is the frequency in Hz, and ωu003d2πf is the angular frequency in 1/s . From this we can see that the capacitive reactance mode Xc of the capacitor is infinite when ωu003d2πfu003d0, so the capacitor is quite open in the DC circuit.
