Series and Parallel Circuits

Front

What is a series circuit?

Back

A circuit in which the components are connected end-to-end, so that the current flows through each component in turn.

Front

What is a parallel circuit?

Back

A circuit in which the components are connected across common points or junctions, providing multiple paths for the current.

What is the formula for equivalent resistance in a series circuit?

Back

R_eq = R1 + R2 + R3 + ... + Rn

Front

What is the formula for equivalent resistance in a parallel circuit?

Back

1/R_eq = 1/R1 + 1/R2 + 1/R3 + ... + 1/Rn

Front

What happens to the total current in a series circuit when more resistors are added?

Back

The total current decreases as more resistors are added.

Front

What happens to the total current in a parallel circuit when more resistors are added?

Back

The total current increases as more resistors are added.

Front

What is Ohm's Law?

Back

V = I * R, where V is voltage, I is current, and R is resistance.

Front

How does resistance affect current in a circuit?

Back

Higher resistance results in lower current for a given voltage.

Front

What is the unit of resistance?

Back

Ohm (Ω)
