Series – Parallel Circuit
Series Circuit:
In a series circuit, components (e.g., bulbs) are connected end-to-end in a single path. If one component fails, the entire circuit breaks, and...
Alternating Current
Alternating current (AC) is a type of electric current where the flow of electrons, or charge carriers, periodically changes direction. Unlike direct current (DC),...
Ohms Law
Ohm’s law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperatures...
Sinusoidal wave
A Sinusoidal wave in the context of Electrical or Electronics Engineering is used to represent a time-varying voltage or current whose average value in...
AC Inductive Circuit
As you can see, the current through the coil is 90° out of phase - and delayed. Why? The periodically alternating current flow...
Resistor in Series & Parallel
Resistors in Series
The same current flows through each resistor one after another.
Total resistance is the sum: R_total = R1 + R2 + R3 +...
AC Voltage
Alternating Voltage (AC Voltage): Voltage that changes direction periodically, usually in a sinusoidal pattern.
A sine wave represents AC voltage and current.
Voltage and current rise...
Square Waveform
What is a square wave
A square wave is a periodic waveform that switches between two levels (for example +A and −A, or “on” and...
Resistor
A simple circuit with a single resistor connected to a voltage source (battery).
Charges move through the resistor from the positive terminal of the source...
Fourier series triangle wave circles
What a triangle wave is
A triangle wave is a periodic waveform that linearly ramps up then linearly ramps down (or vice versa), forming a...
