Kirchhoff Laws
Kirchhoff Current Law
The algebraic sum of all the currents entering and leaving a node is zero. Based on principle of conversation of charge.
Kirchhoff Voltage Law
The algebraic sum of voltages around a loop is zero. Based on principle of conversation of energy.
Voltage division
Series connection is used to divide voltage. Potentiometeres are commonly used to create voltage divider circuits.
Current division
Parallel connection is used to divide current.
