Question

Please help

R1 = 50.0 Ohm and
R2 = 80.0 Ohm. They are
connected in series with a third
resistor, R3, and the total
resistance of the combination is
200 Ohm.
What is the value of R3?
(Unit = Ohm)
No links please

Answer 1

the answer is 70 ohm

Step-by-step explanation:

let me explain

if R1=50.0 ohm

R2=80.0 ohm

and the total resistance=200 ohm

then R3=the total resistance-(R1+R2)

R3=200-(50.0 + 80.0)=70 ohm
