Engineering V max of a RLC Circuit. Where did I go wrong?

AI Thread Summary
The discussion focuses on calculating the maximum voltage (V max) in an RLC circuit. It highlights the importance of using the total impedance of the series circuit, which requires combining the reactances (XC and XL) rather than using them individually. The correct approach involves calculating the total reactance using the square root of the sum of squares of the reactances. Once the impedance is found, dividing the maximum voltage (emax) by this impedance yields the maximum current (I max). Finally, this current can be used to determine V max for each circuit component.

The denominator in each of your voltage calculations should represent the magnitude of the total impedance of the series circuit. You've not combined the reactances to find the total reactance, but just used either XC or XL individually, which doesn't give you the total impedance when they're summed in quadrature (square root of sum of squares).

So find impedence, then divide emax by it to get I max. Then multiply that by R, Xl, and Xc to find my V max for each component ?

That's the idea, yes.
