What is Voltage?

Voltage is defined as the potential difference between the two points in an electric field. The unit of voltage is Volts(V). Voltage is also known as the electrical potential difference. It is a scalar quantity. The voltage in the series circuit is distributed among all the components in the circuit. In a simple series circuit consisting of a battery and two resistors, the voltage across each resistor would be determined by its resistance to the total resistance of the circuit. This principle is called Ohm’s Law, which states that the voltage across a resistor is directly proportional to the current passing through it and its resistance....

What is Series Circuit?

A series circuit is a circuit in which all the components are connected one after another. In a series circuit, the components are connected in a line successively. The current flowing through the series circuit is the same for all the components whereas the voltage is variable in all the components of series circuit. The total resistance is calculated by adding all the resistances in series....

Voltage in a Series Circuit

In a series circuit the applied voltage is divided among the components of the circuit. So, the applied voltage is represented by the sum of the voltages across each component. We know that constant current flows through the components in the series circuit so, we can also apply Kirchoff’s law to find voltage in a series circuit....

Kirchhoff’s Loop Rule and Ohm’s Law Series Circuit

The ohm’s law state that current passing through the conductors between two points is directly proportional to the voltage across two points. In the series circuit where component are connected end to end then the same current passes through each components. Therefore, the voltage drop across each component is proportional to its resistance according to Ohm’s Law....

Conclusion

From the above discussion we can conclude that in series circuit the current is constant, and the voltages is variable across the components connected in series. Voltage in a series circuit can be calculated by adding all voltages across each component of the circuit as the voltage applied in the series circuit is the sum of the voltages across each component. Also, to find voltage in series circuit we can use the current flowing through the circuit and the total resistance in the circuit by using the Kirchoff’s Law....
