Question

The voltages across three resistances R₁. R₂ and Ry connected in series are V₁, V2 and V3, respectively. What is the net voltage V across them if I represents the net current flowing through them?

• A. V= (1/V₁)+(1/V2)+(1/V3)
• B. V=(1/R1)+(1/R2)+(1/R3)
• C. V=R1+R2+R3
• D. V=V1+V2+V3

Answer 1

Answer:

D. V=V1+V2+V3

• The net voltage across the three resistors in series is the sum of the individual voltages.

• V (total) = V1 + V2 + V3
