In a series circuit, the current is the same throughout the circuit. This is because the electrons have only one path to follow, so they must all travel through the same components. The current in a series circuit can be calculated using Ohm’s law, which states that the current is equal to the voltage divided by the resistance.
The current in a series circuit is important because it determines the amount of power that is dissipated by the circuit. The power dissipated by a circuit is equal to the current squared times the resistance. Therefore, a higher current will result in a higher power dissipation.
