Question 1

What is the equation for total energy in an RLC circuit?

A) \\( E = Li^2 + Cv^2 \\)
B) \\( E = \\frac{1}{2}Li^2 + \\frac{1}{2}Cv^2 \\)
C) \\( E = \\frac{1}{2}L^2i + \\frac{1}{2}C^2v \\)

💡 Hint: Look for half the coefficients in variable terms.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If a circuit has an inductor of 5H, a current of 4A, and a capacitor of 15μF charged to 20V, calculate the total energy. What happens if the inductor releases its current fully?

💡 Hint: Split the calculation to find each energy component and consider energy flow.

Challenge 2 Hard

Discuss how you would design a filter using RLC parameters to achieve high frequency selectivity. What energies need to be considered?

💡 Hint: Look at resonance conditions and energy dynamics in RLC circuits.
