Series Resistance
Easyphysics
Equivalent resistance of two resistors R and 2R in series is:
Select the correct option:
Solution
Incorrect! Answer:
3R
In a series combination, the same current flows through all resistors. The total potential drop is the sum of individual drops: Vtotal=IR1+IR2=I(R1+R2) Rseries=R1+R2=R+2R=3R.
