Tugas Fisika

1. in the R-L series network, known R = 6 ohms. when the network is connected to the source of alternating current - back with a 220 volt voltage and frequency anguler 200 rad / s appears to current flow in the range of 20 large induction coil means Amperes (I) is ……..

a. 0,02 henry

b. 0,2 henry

c. 0,04 henry

d. 0,4 henry

e. 40 henry

2. a capacitor with capacitive rektansi 30 ohms is connected in series with a resistor of 40 ohms. when the circuit is connected to the source of alternating current - behind 100 Volts, then the magnitude of the voltage across the resistor (VR) and the voltage on the capacitor (Vc) is……

a. VR =80 V ; VC = 60 V

b. VR =60 V ; VC = 80 V

c. VR =40 V ; VC = 30 V

d. VR =30 V ; VC = 40 V

e. VR =50 V ; VC = 25 V

Jawaban :

1. D 1 : R = 6 ohm

V= 220 Volt

I = 20 Ampere

F Anguler = 200 rad/s

D 2 : Induksi Kumparan :…….?

D 3 : I = V

XL

I = V

2πfL

20 = 220 V

2.3,14.200.L

20 = 220

6,28.200L

20 = 220

1256 L

2512 L = 220

L = 220

2512

L = ……..

2. D 1 : R1= 30 ohm

R2= 40 ohm

V = 100 volt

D2 : VR = ……..?

VC = …….?

D3 : VR = I x Xr

= 30 x 100

= 3000

= 30 Volt

VC = i x Xc

= 40 x 100

= 4000

= 40 Volt

VR = 30 Volt dan VC = 40 Volt ( D )
