What is the effect of adding a resistor in series on total
R
⃗
\vec{R}
R
?
A
Total
R
⃗
\vec{R}
R
decreases because series resistors create more current paths
B
Total
R
⃗
\vec{R}
R
stays unchanged because only
V
⃗
\vec{V}
V
changes in series
C
Total
R
⃗
\vec{R}
R
increases because series resistances add algebraically
D
Total
R
⃗
\vec{R}
R
becomes zero because charge flow bypasses resistors in series
