Consider the circuit to the right: RA "A" with a circle - Ammeter with zero resistance WW E - Battery with zero resistance R5. Seven different resistors connected as shown R2, R5, R7 - Variable resistors where R can change R6 WW For the questions below, answer "Increases", "Decreases", or "Stays the same" and give brief explanation. All questions regarding voltage (potential) changes, consider the magnitude of the change. Do not worry about the sign. R2 A) If R7 increases and the battery is ideal, what happens to the voltage difference between the points A and E? R1 B) If R2 decreases, what happens to the current through R6? C) If R2 decreases, what happens to the current through R3? D) If R2 decreases, what happens to the current through R2? E) If Rs increases, what happens to the voltage drop across R3? F) If Rs increases, what happens to the voltage drop across R4? G) Numbers are not needed to do Parts A - F, but let's now do some numerical calculations. Let all the odd resistances be 100 0, all the even resistances be 200 0, and & = 120 V. Determine the current measured by the ammeter. H) Starting with the values given in Part G, the resistance R5 is then reduced to R5 = 0. Determine the new current measured by the ammeter
