Ohm’s Law, Resistance in Series and Parallel Circuits
Ohm’s Law states that the current through a conductor is directly proportional to the voltage across it and inversely proportional to the resistance.
Kirchhoff’s Current and Voltage Laws
This law states that the total current entering a junction (or node) in an electrical circuit is equal to the total current leaving the junction. This follows the principle of conservation of charge.
RLC Circuits
An RLC circuit consists of a resistor (R), an inductor (L), and a capacitor (C), connected in series or parallel. The circuit's impedance depends on the frequency and the values of R, L, and C.
RL Circuit
An RL circuit consists of a resistor (R) and an inductor (L) connected in series or parallel.
RC Circuit
