Work through problems with immediate feedback

Recall / Warm-Up

Kirchhoff's Voltage Law (KVL) states that in any closed loop of a circuit:

The sum of all voltage drops across components equals the source voltage.

The current entering a junction equals the current leaving a junction.

KVL only applies to simple series circuits with one loop.

The voltage drops across all resistors are equal.
