Kirchoff’s Law
Two laws are provided by Kirchoff to understand the behavior of electrical circuits
(a) Kirchoff’s Current Law:
It states that the total amount of current entering the junction will be equal to the total amount of current leaving the junction. We can also say that every junction follows the law of conservation of charge.
(b) Kirchoff’s Voltage Law:
It states that for any closed network, voltage around a loop is equal to the sum of voltage drop in the same loop and it is equal to zero.
Resistors in Series
Resistors are devices that obstruct the flow of electric current in the circuit. They provide the hindrance to the path of the current which flows in the circuit.
A resistor is a two-terminal electrical component that works by reducing the flow of charge and voltage levels in the circuit. Most of the circuits have one or more resistors to oppose the flow of current and balance the circuit. Most commonly there are two combinations of resistors – Resistors in Series and Parallel.
