An ac circuit has a resistor, capacitor and inductor in series with a 120 v, 60 hz voltage source. the resistance of the resistor is 3 ohms, the inductance of the inductor is 0.01 henry; the capacitance of the capacitor is 0.00075 farads. find the following: (i)-reactance of the capacitor and inductor (ii)-total impedance current (iii)-apparent power real power vi) reactive power vii) power factor angle viii) power factor.

(i) 3.5385 ohm, 3.768 ohm (ii) 39.89 A (III) 4773.857 W (vi) 348 var (vii) 0.9973 (viii) 4.1796°

Explanation:

We have given voltage V =120 volt

Frequency f=60 Hz

Resistance R =3 ohm

Inductance L =0.01 H

Capacitance C =0.00075 farad

(i) reactance of of inductor

(ii) Total impedance

Current

(viii) power factor

(VII)

So power factor angle is 4.1796°

(iii) Apparent power

(vi) Reactive power

answer:

true

explanation:

answer:

in baseband transmission the whole bandwidth of the cable is utilized by a single signal. eg.Ethernet is using Basebands for LAN.

In the broadband transmission, multiple signals are sent on multiple frequencies simultaneously using a single channel. eg.Digital Subscriber Line (DSL)
