Answer:
In a series circuit, the total resistance is equal to the sum of all resistances.
Step-by-step explanation:
The same current passes through each resistor, so each resistor does its job as you would expect.
For Example:
a series circuit has a 2 Ω (ohm) resistor, a 5 Ω resistor, and a 7 Ω resistor. The total resistance of the circuit is 2 + 5 + 7 = 14 Ω.
