circuit parallel Quiz Practice Quiz | Circuit Parallel

Voltage — Voltage remains the same in parallel circuits.

R_total = (R1 * R2) / (R1 + R2) — The formula (R1 * R2) / (R1 + R2) is used for two resistors in parallel.

It increases — Adding branches provides more paths, thus increasing the total current.

They are unaffected. — Parallel circuits provide independent paths; other resistors continue functioning.

Lower — The total resistance is always less than the smallest individual resistance.
