A series circuit is one in which resistors are connected end-to-end so that the same current flows through each resistor. The total resistance in a series circuit is the sum of the individual resistances.
5 Must Know Facts For Your Next Test
In a series circuit, the current is constant throughout all components.
The total resistance in a series circuit is given by $R_{total} = R_1 + R_2 + ... + R_n$.
If one component fails in a series circuit, the entire circuit stops functioning.
Voltage drops across each resistor in a series circuit add up to the total voltage supplied by the source.
Ohm's Law ($V = IR$) applies to each individual resistor in a series as well as to the entire circuit.
