Question
Answer 3 questions on photo. Show all work.
Equation 1:
E- IRL - Ir = 0 VT =IRL E-VT-Ir=0 VT=E-IR From equation (1) if the internal resistance, r, and emf, E, is constant, as more current. I, is drawn from the cell what will happen to the terminal voltage, VT. From procedure Part B when an external resistance RL, loads an EMF source and when RL is equal to the internal resistance of the cell, r, (i.e. RL = r). What is the terminal voltage. VT, in terms of the emf source, E? Write an equation to determine the terminal voltage of a cell, VT using the terms Lad, LT and E std.
Explanation / Answer
Part A ) As cirrent increases, the product I*r increases, and hence, V T decreses.
Part B ) (E)/2
Part C) Terms are not mentioned in the equations. Cant help you there.
