Assuming the circuit is a parallel combination of a resistor and capacitor, the equation for impedance is Z=sqrt(R^2+1/ωC^2) where R is the resistance and C is the capacitance.

From the given diagram, we can see that R=1000 Ω and C=3.3 μF. We also know that ω=2πf where f is the frequency. Since the frequency is not given, we cannot calculate the exact impedance. However, we can make an estimate based on typical values for AC circuits.

Assuming a frequency of 60 Hz (typical for US residential power), we have:

ω = 2π(60) = 377 rad/s
C = 3.3 × 10^-6 F

Plugging these values into the impedance equation, we get:

Z = sqrt((1000)^2 + 1/(377 × 3.3 × 10^-6)^2) = 1822 Ω

Therefore, the closest answer choice is C) 1800 Ω.
