For the circuit shown below, complete the expressions for each mesh in terms of V1, V2, I1, I2, I3, R1, R2, R3, R4, and R5. Note, you do not have to format the subscript. For example V? would be entered in as V1. For mesh 1, 0 = I1(R1+R4) + I2R4 - V1 For mesh 2, 0 = I1(-R4) + I2(-R4-R2-R5) + For mesh 3, 0 = I2R5 + I3(R3+R5) + V2

Questions Show your full algebra, including units and substitutions. Write full sentences in all explanations. 1. The circuit (below) has two batteries providing $V_1$ and $V_2$ of electrical potential, two resistors $R_1$ and $R_2$, and current $I_0$ defined forward in the clockwise direction. (a) Write Kirchhoff's loop rule for loop $abeda$. (b) Write Kirchhoff's loop rule for loop $adcba$. 2. The timing device in an automobile's intermittent wiper system is based on an RC time constant and utilizes a 0.500 µF capacitor and a variable resistor. Over what range must R be made to vary to achieve time constants from 2.00 to 15.0 s? Explicitly write down the steps in the GRASS method. 3. Consider the charging of a capacitor in an RC circuit. Assume the capacitor is uncharged at time t = 0. (a) Compute the fraction of initial current, $I/I_0$, that is flowing through the capacitor at the following times: t = 0, 1$\tau$ (one time constant) 2$\tau$, 3$\tau$, and 4$\tau$. Express your answer as a percent. (b) How many time constants elapse till the current drops to one-half of its initial value?
