Circuit 1 to 6: A large series resistor is required for voltage measurements; a small parallel resistor for cur-
rent measurements.
Fig. 3.6: Circuit 6: Current measurement
with a greater shunt resistance
Circuit 9 to 10: The quotient of collector current divided by base current is the current gain B. If the base
current is known, the moving-coil instrument will display the B value right away.
