Laws

Ohm's Law: voltage across a resistor is proportional to the current through it.

• Voltage = current multiplied by resistance. V = iR

Kirchhoff's Current Law(KCL): the sum of currents entering a node is zero.

Kirchhoff's Voltage Law(KVL): the sum of voltages around a loop is zero.

• Branch: any single element (example: resistor, voltage source, etc...).
• Node: point of connection between two or more branches.
• Loop: closed path in a circuit.
