Volt and ammeter Learning Goal: This problem helps you explore what happens to voltages and currents in a circuit when you connect voltmeters and meters in dwrerent con?gurations. Use the following numerical values in your calculations: R1 = IkQ, R2 = 21:51, R3 = 31:32, R4 = 41:9, R5 = 51:9, Vs = 10V. Figure 1: Circuit consisting of a voltage source V; and ?ve resistors R1 to R5 (21) Redraw the circuit diagram shown in Figure 1 by adding a voltmeter (letter V in a circle and plus and minus signs indicating direction) to measure voltage Vab from node Va (positive) to node Vb (negative). Calculate the value of Vab. You may use a numerical tool such as IPython to solve the ?nal system of linear equations. (b) Suppose you accidentally connect an ammeter in part (a) instead of a voltmeter. Calculate the value of Va}, with the ammeter connected. (0) Redraw the circuit diagram shown in Figure 1 by adding an ammeter (letter A in a circle and plus and minus signs indicating direction) in series with resistor R5. This will measure the current has through R5. Calculate the value of IRS. (d) Your friend accidentally connects a voltmeter in part (c) above, rather than an ammeter. Calculate the value of 1R5 with the voltmeter connected.
