How do you calculate total resistance in Series circuit?

③Resistance: R=R1+R2 (the total resistance in the series circuit is equal to the sum of the series resistances); if n equal-value resistors (R) are connected in series, then Rt=nR Note: The total resistance is greater than any one of the sub-resistances, because the series resistance is equivalent to increasing the length of the conductor.

Why is the current constant throughout a series circuit?

Explanation: Current (I) remains constant throughout a series circuit. This is because the resistors in a series connection do not change or decrease the current flowing through them. They just resist the current.

What is total voltage in a series circuit?

When resistors are connected in series, they must “share” the total voltage of the source. The total voltage in a series circuit is equal to the sum of all the individual voltage drops in the circuit. As current passes through each resistor in a series circuit, it establishes a difference in potential across each individual resistance.
