Question

PROCEDURE rd: the 10Ω, 5 IQ, 6802. Follow to measure the actual resistance of probe each of e explained by your lab instructor, use the Resistance three resistors. Record these measurements difference between the Order the resistors such that Ri <Ry< R. Determine the the coded resistance value. 07: How does this esperimental error compare to the tolerance coded on the the three resistors into the series circuit in Figure 2a, and do not connect the resistors to ghe y. bsing the resistance probe, measure resistances between the points at the ends of the shown in Figure 2a. Record these values. Also find the your m resistances for the parallel circuit (Figure 2b) and the combination circuit (Figure 2e) diference uremernts Compare each measurement with the theoretical equivalent resistance using Figure 2 R, R, R R, R2 lo-n Q8: What equations describe the total resistance for the series, parallel and combina circuit?

Answer 1

The equivalent resistance of series parallel and combined circuit

For circuit a equivalent resistance equation is Req = R_1 + R_2 + R_3 For circuit b 1/Req = 1/R_1 + 1/R_2 + 1/R_3 1/Req = R_2 R_3 + R_3 R_1 + R_1 R_2/R_1 R_2 R_3 Req = R_1 R_2 R_3/R_1 R_2 + R_2 R_3 + R_3 R_1 For circuit c Req = R_1 + R_2 R_3/R_2 + R_3 for circuit a and b, There will be no effect of swapping of resistors, but for circuit c, swapping will effect as Req = R_2 + R_1 R_3/R_1 + R_3 when R_1 = R_2 = R_3 = R then for circuit a Req = 3R for circuit b Req = R/3 for circuit c Req = R + R/2 = 3 R/2
