Question

2 peal We have the circuit shown here R1 R2 I2 R3 E3 2 1 E1 E2 b R4 In this figure, some currents, EMF sources, and resistors take the following values \begin{itemize} \item $I_1 = 1.00 \text{ A}$, \item $E_2 = 7.00 \text{ V}$, \item $E_3 = 3.00 \text{ V}$. \item $R_1 = 4.00 \Omega$. \item $R_2 = 10.00 \Omega$, \item $R_3 = 7.00 \Omega$, and \item $R_4 = 6.00 \Omega$. \end{itemize} The currents are positive if in the direction indicated. The unknown $E_1$ is positive if the polarity is as illustrated here. Negative values are fine, they just indicate that the pictured current is the wrong way or the pictured EMF has a different polarity.

In this figure, some currents, EMF sources, and resistors take the following values
\begin{itemize}
    \item $I_1 = 1.00 \text{ A}$,
    \item $E_2 = 7.00 \text{ V}$,
    \item $E_3 = 3.00 \text{ V}$.
    \item $R_1 = 4.00 \Omega$.
    \item $R_2 = 10.00 \Omega$,
    \item $R_3 = 7.00 \Omega$, and
    \item $R_4 = 6.00 \Omega$.
\end{itemize}
The currents are positive if in the direction indicated. The unknown $E_1$ is positive if the polarity is as
illustrated here. Negative values are fine, they just indicate that the pictured current is the wrong
way or the pictured EMF has a different polarity.

In this figure, some currents, EMF sources, and resistors take the following values

* I1 = 1.00 A,

* E2 = 7.00 V,

* E3 = 3.00 V.

* R1 = 4.00 Ω.

* R2 = 10.00 Ω,

* R3 = 7.00 Ω, and

* R4 = 6.00 Ω.

The currents are positive if in the direction indicated. The unknown E1 is positive if the polarity is as
illustrated here. Negative values are fine, they just indicate that the pictured current is the wrong
way or the pictured EMF has a different polarity.
