Question

A parallel RC circuit has a capacitive reactance of 962 ohms and a resistance of 1200 ohms. What is the impedance of this circuit? 751 ohm or 1254 ohms or 653 ohms or 968 ohm?

Answer 1

The impedance of a parallel RC circuit can be calculated using the following formula:

Z = (R^-1 + Xc^-1)^-1

where Z is the impedance, R is the resistance, and Xc is the capacitive reactance.

Substituting the given values, we get:

Z = (1200^-1 + 962^-1)^-1

Z = (0.000833 + 0.001039)^-1

Z = (0.001872)^-1

Z = 533.33 ohms

Therefore, the impedance of this parallel RC circuit is approximately 533.33 ohms, which is not one of the answer choices given. It is possible that there is an error in the answer choices or the problem statement.
