The capacitance of 10uF is connected with sinusoidal voltage with frequency of 50Hz and 5000Hz successively, and the effective value of voltage is 220V. The capacitive reactance and current of the capacitance in two cases are calculated

Capacitive reactance XC = 1 / 2 π FC

Voltage 220 V, capacitance 10uF, 20uf, 50UF, parallel capacitance equal to the total number of ah?

Series: 1 / C = 1 / 10 + 1 / 20 + 1 / 50: C = 100 / 17 parallel: C = 10 + 20 + 50 get: C = 80

The reactive power Q of capacitor with 5uF is calculated by adding AC voltage of 220V with frequency of 50 Hz

Xc=1/(2pai*50hz*5uf)
Q=u^2/Xc≈75.99var

Given a capacitor installed on a 220 V, 50 Hz AC power supply, the measured current in the circuit is 0.55 a, calculate its capacitance? If the capacitor is connected to a 220 V, 1000 Hz power supply, calculate the current in the circuit? I need the calculation process, and hope that people with the ability to answer for me

1： According to the known conditions, the capacitive reactance XC in the circuit can be obtained as follows: 220 V * 0.55 a = 400 ohm; 2: according to the formula XC = 1 / (2 * 3.14 * f * c), the equation can be obtained as follows: 400 = 1 / (2 * 3.14 * 50 * c); after calculation, C = 1 / 1256 = 0.0008, the unit is farad, and the conversion to micro method is 800 micro method
