University Physics Young and Freedman Chapter 26 Concept Questions and solutions Chapter 26: Pre-chapter Question Q: Is it possible to connect several resistors with different resistors with different resistances so that they all have the same potential difference? If so, will the current be the same through all of the resistors? A: If in parallel, the voltage across each is the same. But because the current across each is different, the resistances are different. 1. Suppose all 3 of the resistors shown in Fig. 26.1 have the same resistance, so R1 = R2 = R3 = R. Rank the four arrangements shown in parts (a) – (d) of Fig. 26.1 in order of their equivalent resistance, from lowest to highest. A: BDCA 2. Subtract equation (1) from equation (2) in Example 26.6. To which loop in Fig. 26.12 does this equation correspond? Would this equation have simplified the solution of Example 26.6? A: c->b->d->a->c 3. You want to measure the current through and the potential difference across the 2-ohm resistor shown in Fig. 26.12.
