The complex circuit below can be analyzed with Kirchhoff's Laws. Current I1, I2, and I3 move through the three branches in the directions shown. Which of the equations doesn't follow from applying the Loop Law to one of the loops? (Assume each loop is done clockwise). A.) E1 - I1R1 - I3R4 - E3 - I1R2 = 0 B.) E3 + I3R4 - I2R3 - E2 = 0 C.) E1 + I3R4 - I2R3 - E2 = 0

FIGURE 4.13 Circuit with two current sources and one voltage source 1. Find the expressions of current i1 i2 and i3 in terms of the current sources ig1 and ig2, and write out the loop of Kirchhoff’s Voltage Law if you make all the current sources in the circuit open. Do not solve the equations.

Figure P 18.26 shows a voltage divider, a circuit used to obtain a desired voltage $\Delta V_{\text { out }}$ from a source voltage $\mathcal{E}$ . Determine the required value of $R_{2}$ if $\boldsymbol{E}$ $=5.00 \mathrm{V}, \quad \Delta V_{\mathrm{out}}=1.50 \mathrm{V},$ and $R_{1}=1.00 \times 10^{3} \Omega .$ (Hint: Use Kirchhoff's loop rule, substituting $\Delta V_{\mathrm{out}}=I R_{2},$ to find the current. Then solve Ohm's law for $R_{2} .)$
