Be able to state and use Ohm’s law and Kirchoff’s current and voltage laws

Repeat Assessment Problem 1 but use the equation of the graphed line to construct a circuit model containing an ideal current source and a resistor.

Problem 1

a) The terminal voltage and terminal current were measured on the device shown. The values of vt, and it, are provided in the table. Using these values, create the straight line plot of vt versus it . Compute the equation of the line and use the equation to construct a circuit model for the device using an ideal voltage source and a resistor.

b) Use the model constructed in (a) to predict the power that the device will deliver to a 25Ω resistor.
