a. What is the ampere rating of the circuits that are provided for the small-appliance loads? _____ b. What is the minimum number of small-appliance circuits permitted by the Code? _____ c. How many small-appliance circuits are included in this residence? ____

For a set of linear algebraic equations in matrix format, Axy, for a unique solution to exist, det(A) should be __________.

How many digits will the 312- and 412-digit displays have?

Reconsider Problem 3.29. If Va,VbandVc are a negative-sequence set, how would the voltage and current relationships change? (a) If C1 is the complex positive-sequence voltage gain in Problem 3.29 and (b) if C2 is the negative sequence complex voltage gain, express the relationship between C1andC2

If, because of some obstruction in a wall space, it is impossible to keep a Type NM cable at least 1 in. (32 mm) from the edge of the stud, then it shall be protected by a metal plate at least in. thick.

When running Type NM cable through a bored hole in a stud, the nearest edge of the bored hole shall not be less than ________ in. from the face of the stud unless the cable is protected by a 116 in. (1.6 mm) metal steel plate(s).

Representing a transmission line by the two-port network, in terms of ABCD parameters, (a) express VS, which is the sending-end voltage, in terms of VR, which is the receiving-end voltage, and IR, the receiving-end current, and (b) express IS, which is the sending-end current, in terms of VR and IR. (a) VS= _________ (b) IS= ________

Transients (surges) on a line can cause spikes or surges of energy that can damage delicate electronic components. A SPD device contains one or more that bypass and absorb the energy of the transient. _________________________________________________
