A coil of inductance 5.0 mH and negligible resistance is connected to the oscillator of the previous problem. Find the peak currents in the circuit for ω=100 s−1\omega = 100 \text{ s}^{-1}, 500 s−1500 \text{ s}^{-1}, 1000 s−11000 \text{ s}^{-1}.

Step-by-Step Verified Solution

**Answer:** 20,4,2 A20, 4, 2 \, \text{A}. **Step-by-Step Explanation:** I0=E0XL=E0ωLI_0 = \frac{E_0}{X_L} = \frac{E_0}{\omega L}. E0=10 VE_0 = 10 \, \text{V}, L=0.005 HL = 0.005 \, \text{H}. For ω=100,500,1000 s−1\omega = 100, 500, 1000 \, \text{s}^{-1}: I0=100.005ω=2000ω AI_0 = \frac{10}{0.005 \omega} = \frac{2000}{\omega} \, \text{A} [citation:6][citation:9].
