1. Please use methods you learned to combine resistors to answer parts (a), (b) and (c) below. In the circuit diagram, note that the half-circle jog that appears at the midpoint of the two diagonal branches indicates that one wire "skips over" the other, i.e., the two wires are not joined electrically. (Adapted from UMF problem 2.42)
(a) Find the equivalent resistance \( R_{\text {eq }} \) for the circuit in Fig. 1-1. All resistances are in ohms.
