The resistance for the network shown in Figure P2.20 between terminals a and b with copen circuited is Rab=50 Ω. Similarly, the resistance between terminals b and c with a open is Rbc=100 Ω,and between c and a with b open is Rca=70 Ω. Now, suppose that a short circuit isconnected from terminal b to terminal c, and determine the resistance between terminal a andthe shorted terminals b–c.
Consider the practical ammeter, described inFigure P2.73, consisting of an ideal ammeter in serieswith a 1-k resistor. The meter sees a full-scaledeflection when the current through it is 30 μA. If wedesire to construct a multirange ammeter readingfull-scale values of 10 mA, 100 mA, and 1 A,depending on the setting of a rotary switch,determine appropriate values of R1, R2, and R3.
In the circuit shown in Figure P2.34, determine theterminal voltage of the source, the power supplied tothe circuit (or load), and the efficiency of the circuit.Assume that the only loss is due to the internalresistance of the source. Efficiency is defined as the ratio of load power to source power.VS = 12 V RS = 5 k RL = 7 k

- Figure P1.27 shows an ammeter (AM) and voltmeter (VM) connected to measure thecurrent and voltage, respectively, for circuit element A. When current actually enters the + terminalof the ammeter, the reading is positive, and when current leaves the + terminalreading is negative. If the actual voltage polarity is positive at the + terminal of the VM, thereading is positive; otherwise, it is negative. (Actually, for the connection shown, the ammeterreads the sum of the current in element A and the very small current taken by the voltmeter. Forpurposes of this problem, assume that the current taken by the voltmeter is negligible.)

In a circuit that contains only resistors in parallel, some of the current in the circuit will go through each branch of the parallel resistors, as dictated by Kirchoff's Junction Rule. Furthermore, the potential difference provided by the battery is the potential difference across each branch of the parallel resistors (notice there is no potential drop between the branches). Assume the batteries supply a potential difference of AV = 3.0 V, and use Ohm's Law along with the currents measured through resistor R1 in circuits 4a, 4b, and 4c to determine the effective resistance in this branch (the branch that includes R1) of each circuit. Please show the calculation of each. R1 = 150 ohm, R2 = 230 ohm R3 = 270 ohms (don't believe question should need these but providing anyways)arrow_forward
