## What is alternating current (AC): The basic AC definitions

Alternating current (AC) is the type of electrical current which changes its direction and magnitude every moment.

Alternating current (AC) is the type of electrical current which changes its direction and magnitude every moment.

Superposition Theorem state that the voltage across an element in a linear electric circuit is the algebraic sum of the voltages across that element due to each independent source …

In contrast to a practical voltage source, an imaginary deal source provide constant voltage regardless of load current because of no internal resistance. While ideal current source provides a …

Star Delta Transformations and Delta Star Transformations allow us to convert resistances or impedances connected together at three different nodes from one type of connection to another and vice …

Maximum Power Transfer Theorem state that maximum power will transfer from source to load if and only if the load resistance is equal to source internal resistance. The theorem …

Source transformation or conversion is a technique to replace a voltage source with a current source for circuit simplification and vice versa.

Norton Theorem reduces any two port circuit to a Norton Resistor, a load resistor, and a current source in parallel. Where Thevenin Theorem incorporates voltage source in series.

According to Thevenin Theorem, a complex circuit is reduced to two resistor network, Thevenin Resistor, and Load resistor and a Thevenin Voltage source to avoid redundant computation to analyze …

Resistors are said to be parallel if there is only one path for the flow of current. The total resistance in parallel is less than the individual resistors in …

Resistors are in series if there is only one path for the flow of current. That's why current remain same for all the resistors in series.
