A 2.0 mH inductor is connected in parallel with a variable capacitor. The capacitor can be varied from 100 pF to 200 pF. What is the range of oscillation frequencies for this circuit?
The range of oscillation frequencies is 3.53 Hz - 5.03 Hz.
We have given that, a 2.0 mH inductor is connected in parallel with a variable capacitor. The capacitor can be varied from 100 pF to 200 pF.
Here, = Oscillation frequency
As the capacitance vary between two values, we will calculate oscillation frequency for both values separately.
Calculating value for
Now we will calculate for
So the range of oscillation frequency is 3.53 MHz - 5.03 MHz.
3. I A 10-cm-long wire is pulled along a U-shaped conducting rail in a perpendicular magnetic field. The total resistance of the wire and rail is . Pulling the wire at a steady speed of causes of power to be dissipated in the circuit.
a. How big is the pulling force?
b. What is the strength of the magnetic field?
