R, and R2 are two parallel resistors that are supplied by a current source of I A. If an ammeter with internal resistance Ra is used to measure the current l, which is passing through the resistor R2, show that it is the percentage error in 1, where x = R+R2 Comment on your results. 1+ Ra 2+x If another ammeter is added to the circuit to measure the current through Ry, show that is the percentage error in 12 if the internal resistance of the added ammeter is Ra. Draw the percentage error as a function of assuming that x is constant. Comment on the results. Justify the case where = 1. R: R1
