1. Set up a slide-wire Wheatstone bridge circuit as in Fig. 1 a, using the previous small known resistance R as Rx. Leave the switch open until the instructor checks the circuit. The decade resistance box is used for R, and R. Set Rs to be initially equal to R. Use the 100 2 resistor as R Contact is made to the wire by sliding contact key b. Do not slide the key along the wire while it is pressed down. This will scrape the wire, causing it to be nonuniform. The wires connecting the resistances and the bridge should be as short as possible. 2. Turn on the power supply and balance the bridge by moving the slide wire contact until the galvanometer reads zero. Disconnect the power supply from the circuit and record L1, L2, and R. Record your values in Table 1. 3. Repeat steps 1 -2 for R, setting of (a) 2R, and (b) 0.5 R.. 4. Repeat steps 1-3 for R~ 1000.0 2. Record your values in Table 2 5. For Tables 1 and 2, compute the value of R, and find the average value. Compare the average value with the accented value by finding the nercent error
