Kirchhoff's Current Law
The sum of all currents entering a node is equal to the sum of all currents leaving the node.
Kirchhoff's Voltage Law
The directed sum of the electrical potential differences around a loop must be zero.
Ohm's Law
The voltage across a resistor is equal to the product of the resistance and the current flowing through it.
Nortan's Theorm
Any network of voltage or current sources and resistors is electrically equivalent to an ideal current source in parallel with a single resistor.
Thévenin's Theorm
Any network of voltage or current sources and resistors is electrically equivalent to a single voltage source in series with a single resistor.
Superposition Theorm
In a linear network with several independent sources, the response in a particular branch when all the sources are acting simultaneously is equal to the linear sum of individual responses calculated by talking one independent source at a time.
Resistance
The force against the flow of the electrons.
Capacitor
A device that stores a charge.
Inductor
Has an ability to store a charge in a magnetic field (whereas a capacitor stores it in an electric field) and has the ability to maintain a constant current in a circuit(whereas a capacitor can maintain a constant voltage). This means that an inductor can easily conduct DC (whereas a capacitor can easily conduct AC), however if AC is put through an inductor, the magnetic field will grow and collapse with the rise and fall of current, which tends to oppose the flow of AC through an inductor.
