Question : 133 of 200

Marks: +1, -0

The capacitive reactance of a circuit is 60 Ohms, when it is supplied with a 50 Hz supply. What will be the value of capacitive reactance (in Ohms) of the same circuit, if it is supplied with a 60 Hz supply?

Validate

Solution:

Capacitive Reactance

X_C= 1 /{2π\fc }

60= 1 /{2π×50×C }

X_C={60×50}/60=50Ω
