Resistors in series and parallel example let us calculate the equivalent resistance for the below circuit which consists of 7 resistors r1 4. I think it is incorrect to say that a switch and a light bulb is an example of a series circuit, though its technically correct i guess. When there is only one bulb, the lamp still works and to explain more we can sary house wiring. The parallel rlc circuit is the exact opposite to the series circuit we looked at in the previous tutorial although some of the previous concepts and equations still apply. Lets take a look at some examples of parallel circuits that demonstrate these principles. Here we have a series circuit with a battery, an led and a resistor.
