Any switch in your house that controls a single bulb is a series circuit. The switch and bulb are in series.
If you have a dimmer switch, the dimmer is in series with the bulb - kinda like a variable resistor - and reduces the voltage/current/brightness of the bulb.
If a switch controls multiple bulbs, they would be in parallel.
Many real world electronic devices are just collections of wires, resistors, capacitors, and batteries, forming circuits that do something (flashlights, toasters, blowdryers, radios, amplifiers,...) It's important to understand (and predict) the currents and voltages in such circuits. E.g., consider first a simple “flashlight circuit”: The “R” here might represent the resistance of the flashlight bulb. Here, V=IR1, or I = V*(1/R1) Now consider a slightly more complicated circuit: These resistors are in series. There will be a voltage drop V1= I*R1 across the first resistor,
and V2 = I*R2 across the second. The TOTAL voltage drop from top to bottom is V = V1+V2 = I*(R1+R2)
so,we cannot give definite no. but can say but it is used almost everywhere
