The i-v characteristics for the electrical component C on the right of terminals a-b is described by the linear equation: $I = 0.255 V + 0.494$ On the left, a current source, $I_s = -0.441$ A, and a resistor, $R = 86 \Omega$ are connected to the a-b terminals as shown. (pay attention to all the negative signs that might be missed) a + $I_s$? R V C b a) What is the IV equation for the circuit on the left of terminals a-b? $I = \text{________} V + \text{________}$ (within three significant digits) b) What are the numerical values for V and I that occur when the two circuits are joined as shown above? $V = \text{________} V$ $I = \text{________} A$ (within three significant digits) What is the power, and state what the component is. $Power \text{ (of component C)} = \text{________} W$ (within three significant digits) Component C is: $\circ$ a source $\circ$ a load $\circ$ neither
