Series and parallel circuit connections can be made in thousands of different ways and with all types of electronic components. If each element is in parallel with every other element, it is called a parallel circuit. The elements in this circuit are the compressor and the temperature control switch. Here we have a series circuit with a battery, an led and a resistor. Series parallel circuit series parallel circuit examples. A typical example of a load is a single light bulb. So for example, in the case of dc, the circuits can also be divided into three groups, such as series dc circuit, parallel dc circuit and series and parallel circuit.
Youll also learn to apply the ohms law in series circuits. Most electronic circuit designers first learn how to use resistors, batteries and leds in series and parallel connections. Circuits consisting of just one battery and one load resistance are very simple to analyze, but they are not often found in practical applications.
