CAPACITOR IN SERIES AND CAPACITOR IN PARALLEL

Table of Contents

Before go through capacitor in series and capacitor in parallel first check the relation given below

Capacitors act like a short circuited at high frequencies and an open circuited at low frequencies. By the Capacitive reactance formula:

Xc = 1 / 2 π f C

where,

Xc → reactance in ohms (W)

f → frequency in hertz (Hz)

C → capacitance in farads (F)

If capacitor act as open circuit for DC or low frequency signals then how it can be used in DC circuits?

Here are two cases:

In this situation, AC is able to pass through, but DC gets blocked. This is commonly called a coupling capacitor.

In this situation, DC is able to get through, but AC is shorted to ground causing it to be blocked. This is commonly called a decoupling capacitor.

Now let implement this within the series and parallel circuits (don’t worry about resistor we will see cover this in next topic)

FOR EXAMPLE

In series we can see led will not going to glow

In parallel we can see led will glow
