He capacitor can withstand a peak voltage of 550 VV . If the voltage source operates at the resonance frequency, what maximum voltage amplitude can it have if the maximum capacitor voltage is not exceeded?

The maximum voltage is 39.08 V.

Explanation:

Given that,

Voltage = 550 V

Suppose, In an L-R-C series circuit, the resistance is 400 ohms, the inductance is 0.380 Henry, and the capacitance is

We need to calculate the resonant frequency

Using formula of resonant frequency

Put the value into the formula

We need to calculate the maximum current

Using formula of current

Put the value into the formula

We need to calculate the impedance of the circuit

Using formula of impedance

At resonant frequency ,

So, Z = R

We need to calculate the maximum voltage

Using formula of voltage

Put the value into the formula

Hence, The maximum voltage is 39.08 V.
