What happens to the total resistance if two resistors are connected in series?
The total resistance is the sum of the two resistors.
The total resistance is the product of the two resistors.
The total resistance is smaller than either resistor.
The total resistance is the difference between the two resistors.
Explicación
When resistors are connected in series, the total resistance is the sum of each individual resistance.
