Homework Equations
Kirchhoff's Laws (i.e. current law, voltage law).
The Attempt at a Solution
Ok, I know that I...
reply
Is this right?
i is the current
\begin{align*}
2V_x+V_x+2i+i&=15\\
3(5\cdot i)+2i+i&=15\\
i&=\frac{15}{18}=\frac{5}{6}\;A
\end{align*}
V=I\cdot R=\frac56 \cdot 5=\boxed{\dfrac{25}{6}\;V}
Homework Statement
Find V_x in the circuit.
Homework Equations
\displaystyle{\sum V_i=0}
The Attempt at a Solution
I tried to add all of the voltages and label the 2 ohm res V1 and 1 ohm res V2.
Then I did:
V_x+V_1-15+V_2+2V_x=0
3V_x+V_1+V_2=15
but then I couldn't find any other...
