tolong dijwb yach soalnya mau diperiksa besok

A] Diket :R1= 4
R2 = 6
R3 =12
Dit : R pengganti =....?
Penyelesaian :
1/Rp=1/R1+1/R2+1/R3
=1/4+1/6+1/12
=3+2+1/12
=6/12
Rp=12/6 = 2 ohm

B]Diket : R = 2
V = 3
Dit : I=...?
Penyelesaian :
I =V/R
=3/2
=1,5 A

3) Diket : R1 = 1
R2 = 4
I = 200mA = 0,2 A
Dit : V =....?
Penyelesaian :

[Pertama tama cari Rtot]
Rtot =R1+R2
=1 + 4
= 5 ohm

V = I.R
= 0,2.5
=1 V
