Question

While traversing a closed loop, a source gives a rise of $12\,	ext{V}$ and three elements cause drops of $2\,	ext{V}$, $3\,	ext{V}$, and $4\,	ext{V}$. What is the voltage drop across the fourth element?

Accepted Answer

C. $3\,	ext{V}$

By KVL, total drops equal total rise. The source rise is $12\,	ext{V}$. Known drops sum to $2+3+4=9\,	ext{V}$, so the remaining drop is $12-9=3\,	ext{V}$.

Answer

$1\,	ext{V}$

Answer

$2\,	ext{V}$

Answer

$5\,	ext{V}$
