Shown below is a DC circuit that contains a number of switches. The resistance of each switch is negligible when closed. All of the connecting wires may be considered to have zero resistance. All of the resistors shown are identical. The circuit contains an ideal ammeter. The diagram shows all of the switches open. Beside the diagram are eight different switch configurations for the circuit. Rank these configurations in terms of the ammeter reading. That is, put first the configuration...

A circuit you’re building needs an ammeter that goes from 0 mA to a full-scale reading of 50.0 mA. Unfortunately, the only ammeter in the storeroom goes from 0 μA to a full-scale reading of only 500 μA. Fortunately, you can make this ammeter work by putting it in a measuring circuit, as shown in Figure 65 This lets a certain fraction of the current pass through the meter; knowing this value, you can deduce the total current. Assume that...

A circuit you're building needs an ammeter that goes from 0 mA to a full-scale reading of 60.0 mA . Unfortunately, the only ammeter in the storeroom goes from 0μA to a full-scale reading of only 500μA. Fortunately, you've just finished a physics class, and you realize that you can make this ammeter work by putting a resistor in parallel with it, as shown in the figure (Figure 1) . You've measured that the resistance of the ammeter is 90.0...
