Solution

To find the peak current in the circuit, we need to follow these steps:

  1. Determine the angular frequency (ω): The angular frequency is given by: ω=2πf \omega = 2\pi f where f f is the frequency of the AC generator. Given f=60 f = 60 Hz, ω=2π×60=120πrad/s \omega = 2\pi \times 60 = 120\pi \, \text{rad/s}

  2. Calculate the capacitive reactance (X_C): The capacitive reactance is given by: XC=1ωC X_C = \frac{1}{\omega C} where C=300 C = 300 mF = 0.300 F. Substituting the values, XC=1120π×0.300=136π0.00884Ω X_C = \frac{1}{120\pi \times 0.300} = \frac{1}{36\pi} \approx 0.00884 \, \Omega

  3. Determine the impedance (Z) of the series RC circuit: The impedance is given by: Z=R2+XC2 Z = \sqrt{R^2 + X_C^2} where R=10.0Ω R = 10.0 \, \Omega . Substituting the values, Z=10.02+0.008842100+0.000078100=10.0Ω Z = \sqrt{10.0^2 + 0.00884^2} \approx \sqrt{100 + 0.000078} \approx \sqrt{100} = 10.0 \, \Omega

  4. Calculate the peak current (I_0): The peak current is given by: I0=V0Z I_0 = \frac{V_0}{Z} where V0=110 V_0 = 110 V (peak voltage). Substituting the values, I0=11010.0=11.0A I_0 = \frac{110}{10.0} = 11.0 \, \text{A}

Therefore, the peak current in the circuit is 11.0 11.0 A.
