This physics video tutorial provides a basic introduction into kirchoff's voltage law which states that the sum of all the voltages in a loop must add to zero. This video explains how to solve kcl circuits by using kirchoff's loop rule to calculate the current flowing in a series circuit with multiple batteries / voltage sources. This video also explains how to calculate the electric potential at every point using ohm's law. This video contains plenty of examples and practice problems.

This physics video tutorial provides a basic introduction into parallel circuits. it explains how to calculate the electric current flowing through each resistor in a parallel circuit. The voltage across each resistor is the same in a parallel circuit and it's equal to the voltage of the battery. This tutorial explains how to solve parallel circuits with two resistors and with three resistors. It discusses how to calculate the power delivered by the battery to the circuit and the power absorbed by each resistor. Kirchoff's current law applies to parallel circuits which states that the total current entering a junction must equal to the total current leaving the junction - this is also known as the junction rule of kirchoff's law. This video uses the principles behind ohm's law to calculate the voltage, current, resistance, and power of an element or device in a circuit.
