The question is: So 2E = I * R E = I * (R + 1Mohm) ^ Is that correct so far? I was trying to plug in values to see if this actually worked, but I'm not having any luck? 10v = .00001A * 1Mohm 20v = .00001A * 2Mohm Should the current be a constant in this? Cause when you add resistance in the equation, the voltage number goes up, not down, if the current stays the same? What am I doing wrong?
