A) 3.18 MHz
B) 15.9 MHz
C) 1.59 MHz
D) 3.98 MHz
E) 2.54 Mhz

Quizplus · Accepted Answer

Reactance of a capacitor (Xc) is given by Xc=1/(2πfC), where f is the frequency and C is the capacitance.

Given Xc = 1000 Ω and C = 100 pF, we can rearrange the equation to solve for f:

f = 1/(2π Xc C)

f = 1/(2π x 1000 Ω x 100 pF)

f = 1.59 MHz

Therefore, the correct answer is choice C) 1.59 MHz.
