Current Question (ID: 20597)

Question:
$\text{In a series } RLC \text{ circuit, } R = 80 \, \Omega, \, X_L = 100 \, \Omega, \, X_C = 40 \, \Omega. \text{ If the source voltage is } 2500 \cos(628t) \, \text{V, the peak current is equal to:}$
Options:
  • 1. $5 \, \text{A}$
  • 2. $25 \, \text{A}$
  • 3. $10 \, \text{A}$
  • 4. $12 \, \text{A}$
Solution:
$Z = \sqrt{R^2 + (X_L - X_C)^2}$ $= \sqrt{80^2 + (100 - 40)^2}$ $= 100 \, \Omega$ $\Rightarrow \, I_0 = \frac{V_0}{Z} = \frac{2500}{100} \, \text{A} = 25 \, \text{A}$
