Full explanation please

Make three plots using Excel: 1. Voltage vs current for the linear resistor data (voltage on vertical axis, current on horizontal). Add a linear trendline with the equation and R² value shown. 2. Voltage vs current for the lightbulb data (voltage on vertical axis, current on horizontal). 3. A plot showing both curves on the same set of axes (voltage on vertical axis, current on horizontal).

A 40 amp branch circuit is run a long distance requiring a voltage drop calculation which increases the copper ungrounded conductors from a #8 to a #3. What size is the copper equipment grounding conductor required to be?

Answer question clearly and fully. Make sure I can properly read out the steps. Include any and all equations used during the solving process.

leaving a freevway. Current from the opposite side must travel further, weakening the potential on that side. This creates a potent the motor in that direction, causing the motor to spin. O Only the side where the switch is closed forms a cormplete circuit, so the motor must spin in that direction.
