Engineering Circuits Problem: Find Voltage Across Resistor, Capacitor, Inductor

[Red_CCF]

Homework Statement

A circuit with a resistor, capacitor, and inductor all connected in parallel with resistance = 5000 ohm, inductance = 1.25H and capacitance = 8nF, find the voltage across the components.

Homework Equations

v = L*di/dt, i = C*dv/dt, v = iR

The Attempt at a Solution

I'm not sure what to do, I tried both node-voltage and mesh current but can't get at a solution

Hi Red_CCF!

Don't we need some more information?

What is the power supply (and if it's AC, what is the frequency)?

Hi

Thanks for the response. I uploaded the problem with the drawing of the circuit. They just drew the three components connected in parallel, defined an unknown voltage across them and asked for the voltage response.

Presumably the "response" required will be that due to a unit step or impulse applied to the circuit.

You should investigate the concept of damping for oscillations. You should be able to find the expression for the damping factor for the parallel RLC circuit and determine whether this circuit is underdamped, critically damped, or overdamped.

Thanks very much. I completely forgot about the formula for RLC circuits
