What is the impedance of a series combination of a 50-ω resistor, a 5.0-μf capacitor, and a 10-μf capacitor at a frequency of 2.0 khz?

55.92 ohm

Explanation:

R = resistance of the resistor = 50 ohm

f = frequency = 2000 Hz

= Capacitance of first capacitor = 5.0 x 10⁻⁶ F

= Capacitance of second capacitor = 10 x 10⁻⁶ F

= Series combination of capacitance

Series combination of capacitance is given as

= capacitive reactance of series combination

Capacitive reactance of capacitor is given as

ohm

R = resistance of the resistor = 50 Ω

z = impedance of the circuit

Impedance is given as

z = 55.92 ohm

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
