if Xc = 7,500 and the resistance is 10,000 in a series RC circuit , what is the impedance of the circuit?
mr_godi [17]

Answer:

The impedance of the circuit = 12500 Ω

Explanation:

<em>Impedance:</em> This is the overall opposition to the flow of current in an a.c circuit by any two or all of the three circuit elements.(R, L, C) is called <em>impedance.</em>

<em>The  S.I unit of Impedance is Ohms. (Ω), It can be represented mathematically as</em>

Z = √(Xc² + R²).................... Equation 1

Where Z = impedance, Xc = reactance of the capacitor, R = resistance of the  resistor.

<em>Given: Xc = 7500 Ω, R = 10000 Ω</em>

<em>Substituting these values into equation 1,</em>

<em>Z = √(7500² + 10000²)</em>

<em>Z = √(56250000 + 100000000)</em>

<em>Z = √(156250000)</em>

Z =12500 Ω

Therefore, The impedance of the circuit = 12500 Ω
