An ammeter is used as shown in Figure P2.78. The ammeter model consists of an ideal ammeter in series with a resistance. The ammeter model is placed in the branch as shown in the figure. Find the current through R5 both with and without the ammeter in the circuit for the following values, assuming that RS = 20 ? , R1 = 800 ? , R2 = 600 ? , R3 = 1.2 k? , R4 = 150? , and vS = 24 V.
Find:
The current through both with and without the ammeter, for the following values of the resistor R5:
a. R5 = 1 k?
b. R5 = 100?
c. R5 = 10?
d. R5 = 1?
