Question 1.
What are the two components of an LC oscillator?
Show hintHide hint
Think about electrical circuits.
Question 2.
What does the charge (q) represent in an LC circuit?
Show hintHide hint
Recall the role of capacitors.
3Question 3.
What components are involved in an LC oscillator?
- Inductor and resistor
- Capacitor and transformer
- Inductor and capacitor
- Capacitor and diode
Show hintHide hint
Think about the basic circuit design.
4Question 4.
The angular frequency of an LC circuit is related to which two quantities?
- Inductance and resistance
- Capacitance and inductance
- Resistance and voltage
- Voltage and charge
Show hintHide hint
Focus on the formula for angular frequency.
Question 5.
An LC circuit has an inductor of 3 mH and a capacitor of 15 μF. Determine the frequency of oscillation.
Show hintHide hint
Apply the formula for frequency derived from angular frequency.
Question 6.
In a certain LC circuit, if the charge reaches a maximum value of 5 C at t=0, find the current at t= $\frac{T}{4}$ where T is the period of oscillation.
Show hintHide hint
Remember that at T/4, the charge reaches zero and thus maximum current flows.
