CAPACITOR IN SERIES AND CAPACITOR IN PARALLEL

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?

CAPACITOR IN SERIES AND CAPACITOR IN PARALLEL

Here are two cases:

CAPACITOR IN SERIES WITH SIGNAL

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

capacitor in series
Logic – Capacitor in Series

CAPACITOR IN PARALLEL WITH SIGNAL

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.

capacitor in parallel
Logic – Capacitor in Parallel

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

CAPACITOR IN SERIES – LED WILL NOT GLOW

Capacitor in Series Circuit
Circuit – Capacitor in Series

CAPACITOR IN PARALLEL – LED WILL GLOW

capacitor in parallel circuit
Circuit – Capacitor in Parallel
