Finding Frequency oscillation in Hz

Click For Summary
SUMMARY

The discussion focuses on calculating the frequency of oscillation in Hertz (Hz) using the formula \( f = \frac{1}{2\pi \sqrt{L \cdot C}} \). The values provided are inductance \( L = 0.1 \) and capacitance \( C = 0.0003 \). The user struggles to arrive at the correct answer of 91.89 Hz due to a misunderstanding in the calculation process, particularly in handling the units and the values of L and C. The correct calculation yields a frequency of approximately 91.89 Hz when the values are correctly substituted into the formula.

PREREQUISITES
  • Understanding of electrical components: inductance and capacitance
  • Familiarity with the formula for frequency in oscillating circuits
  • Basic algebra skills for manipulating equations
  • Knowledge of units in electrical engineering
NEXT STEPS
  • Review the formula for frequency in LC circuits: \( f = \frac{1}{2\pi \sqrt{L \cdot C}} \)
  • Practice unit conversion and dimensional analysis in electrical calculations
  • Explore the impact of varying inductance and capacitance on frequency
  • Learn about resonance in RLC circuits and its applications
USEFUL FOR

Students studying electrical engineering, hobbyists working with oscillating circuits, and anyone involved in designing or analyzing LC circuits.

Homework Statement



Hi there.. I would really love a but of help with this question. It seems like the simple sort but there is one step that I seem to be missing.. I need the answer in Hz so basically its this .. one over 2∏ times √ of inductance times Capacitence. So here is the prob I can not seem to reach the answer of 91.89hz
Question
1/(2∏*√L*C) L = 0.1 C = 0.0000.30
∴
1/(6.283*√(0.1*0.000.30)
∴
1/(0.01882475)


And this is all I got. I have tried many different ways to get there but not making it..If there is anyone that could point me in the ( am sure very simple step )direction I would be very grateful. thanks very much.

This is Quite the norm sort of

L and C have units. You need to get into the habit of aways including their units.

What is this number in words, please: 0.0000.30
