Question

Explain the circuit connection in the series circuit.

Answer 1

Series circuit

1. A circuit made up of different parts connected in series is known as a series circuit.
2. In other words, the components connected in series are connected in one "electrical" way, and each component has the same capacity, equal to the current in the network.
3. The voltage across the entire network is equal to the sum of the voltage in each component.

A simple series circuit

Explanation:

1. A simple series circuit, which includes a power source and three resistance units is shown in the figure above.
2. If we join three resistance in series by end-to-end connection. Then their combined resistance $\left(R\right)$ will be,
   $R=R_1+R_2+R_3$, Where $R_1,R_2,R_3$ are resistance of each resistor as shown above.
   So according to Ohm's law, $V=IR=I\left(R_1+R_2+R_3\right)$
3. There is only one path for the current to flow in the series circuit. In other words, a series circuit provides a single path between any two points.
4. These circuits have the advantage of making each component very dependent on the other components.
5. This means that if one component is removed, all of the components turn off.

Hence, in a series circuit, all the resistances are connected end to end.
