The correct Answer is:
To solve the problem step by step, we need to analyze the given circuit conditions and apply the relevant formulas for alternating current circuits. ### Step 1: Understand the given conditions We are given that: - \( X_L = \frac{X_C}{2} = R \) From this, we can derive: - \( X_L = R \) - \( X_C = 2R \) ### Step 2: Calculate the impedance \( Z \) The total impedance \( Z \) in an AC circuit with resistance \( R \), inductive reactance \( X_L \), and capacitive reactance \( X_C \) can be calculated using the formula: \[ Z = \sqrt{R^2 + (X_L - X_C)^2} \] Substituting the values we have: \[ Z = \sqrt{R^2 + (R - 2R)^2} \] \[ Z = \sqrt{R^2 + (-R)^2} \] \[ Z = \sqrt{R^2 + R^2} = \sqrt{2R^2} = R\sqrt{2} \] ### Step 3: Calculate the peak current \( I_0 \) The peak current \( I_0 \) can be calculated using Ohm's law for AC circuits: \[ I_0 = \frac{V_0}{Z} \] Substituting the expression for \( Z \): \[ I_0 = \frac{V_0}{R\sqrt{2}} \] ### Step 4: Simplify the expression To express \( I_0 \) in a more manageable form, we can rewrite it as: \[ I_0 = \frac{V_0 \sqrt{2}}{2R} \] ### Conclusion Thus, the peak value of the current \( I_0 \) is: \[ I_0 = \frac{V_0 \sqrt{2}}{2R} \]
