Answer:
The peak voltages across each capacitor are 6.0 V, 4.0 V and 2.0 V.
Explanation:
Given that,
Amplitude = 12.0 V
Frequency = 6.3 kHz
Suppose, Three capacitors are 2.0 μF, 3.0 μF and 6.0 μF
We need to calculate the equivalent capacitor
Using formula of series
Put the value into the formula
We need to calculate the charge
Using formula of charge
Put the value into the formula
The charge will be same in each capacitor because the capacitors are connected in series.
We need to calculate the voltage across first capacitor
Using formula of voltage
Put the value into the formula
We need to calculate the voltage across second capacitor
Using formula of voltage
Put the value into the formula
We need to calculate the voltage across third capacitor
Using formula of voltage
Put the value into the formula
Hence, The peak voltages across each capacitor are 6.0 V, 4.0 V and 2.0 V.
