What would the capacitive reactance be in a circuit if the capacitor is 0.00019 farads and a frequency 20 Hz ?

Respuesta :

Answer:

41.9 ohm

Explanation:

The capacitive reactance is the resistance offered by the capacitor in an ac circuit .

Its unit is ohm.

It depends on the frequency of ac circuit.

C = 0.00019 farad

f = 20 hz

The relation between the capacitive reactance and the capacitance is given by

[tex]X_{c}=\frac{1}{2\times \pi \times f\times C}[/tex]

[tex]X_{c}=\frac{1}{2\times 3.14 \times 20\times 0.00019}[/tex]

Xc = 41.9 ohm

Thus, the capacitive reactance of the circuit is 41.9 ohm.
