question 45

Short Answer

In questions find the matrix that represents the given relation. Use elements in the order given to
determine rows and columns of the matrix.
- $$R \text { on } \{ - 2 , - 1,0,1,2 , \} \text { where } a R b \text { means } a ^ { 2 } = b ^ { 2 } \text {. }$$

Definitions:

Parallel LC Circuit

A circuit configuration that contains both inductance (L) and capacitance (C) in parallel, which can exhibit resonance at a specific frequency where reactive effects cancel each other.

Impedance

A measure of the total opposition that a circuit presents to alternating current, including both resistance and reactance.

Apparent Power

The total power within an AC circuit, represented as VA (volt-amperes), which combines both real power and reactive power.

RLC Parallel Circuit

An electrical circuit consisting of a resistor (R), inductor (L), and capacitor (C) all connected in parallel, affecting the circuit's overall impedance and resonance frequency.
