Resistors are said to be in series whenever the current flows through the resistors sequentially.
When it comes to electrical engineering, solving circuits is a fundamental skill.
Before beginning this instructable it is important to note the three main aspects of a circuit being current, voltage, and total resistance.
In a series circuit, the equivalent resistance is the algebraic sum of the resistances.
The current through the circuit can be found from Ohm’s law and is equal to the voltage divided by the equivalent resistance.
