Resistances 66064

Two resistors with resistances of 40 ohms and 60 ohms are connected in series and connected to a voltage of 150V.
A) the total resistance
B) current in the circuit
C) voltage on both resistors

Correct answer:

R =  100 Ω
I =  1.5 A
U1 =  60 V
U2 =  90 V

Step-by-step explanation:

R1=40 Ω R2=60 Ω U=150 V  R=R1+R2=40+60=100 Ω
I=RU=100150=23 A=1.5 A
U1=R1 I=40 23=240 3=2120=60 V
U2=R2 I=60 23=260 3=2180=90 V
