Basic Electrical Engineering DC Network Theorem

The current can be determined using the formula $I = \frac{V}{R}$, where $V$ is the voltage and $R$ is the resistance.

KCL states that the total current flowing into a junction must equal the total current flowing out of that junction.

KVL indicates that the sum of all voltage drops around a closed loop in a circuit is zero, providing a method to analyze voltage in loops.
