You are working as an electrician in a large steel manufacturing plant, and you are in the process of doing preventive maintenance on a large DC generator. You have megged both the series and shunt field windings and found that each has over 10 M to ground. Your ohmmeter, however, indicates a resistance of 1.5 across terminals S1andS2. The ohmmeter indicates a resistance of 225 between terminals F1andF2. Are these readings normal for this type machine, or is there a likely problem? Explain your answer.
Which of the following is the standard by which electrical installations are measured in the United States? a. National Electrical Code b. United Electrical Code c. Basic Electrical Code d. none of the above
For residential water heaters, the Consumer Product Safety Commission suggests a maximum temperature setting of ___________ F (_____________ C). Some states have laws stating a maximum temperature setting of ____________ F (________________ C).
A good rule-of-thumb to estimate the expected life of a motor, a ballast, or other electrical equipment is that for every ____________ C above rated temperature, the expected life will be cut in __________________.
1. What is the dielectric?
Consider the circuit shown in Figure 2.23 in time domain. Convert the entire circuit into phasor domain.
What basic concept is used in a digital meter to calculate the circuit characteristics being measured? a. Watts law b. Volts law c. Amps law d. Ohms law

Given the complex numbers A1=630 and A2=4+j5, (a) convert A1 to rectangular form: (b) convert A2 to polar and exponential form: (c) calculate A3=(A1+A2), giving your answer in polar form: (d) calculate A4=A1A2, giving your answer in rectangular form: (e) calculate A5=A1/(A2*) giving your answer in exponential form.
Select the best answer for each of the following. LVP is used mainly for a. fans. b. air compressors. c. pumps. d. protection of the operator.
A major hazard involved with water heaters is that they operate under whatever pressure the serving water utility supplies. Water stays liquid at temperatures higher than the normal boiling point of 212F (100C). If the high-temperature limit control failed to operate for whatever reason, should a pipe burst or a faucet be opened, the pressure would instantly drop to normal atmospheric pressure, causing the superheated water to turn into ______________ that could result in ______________. To prevent this from happening, water heaters are equipped with pressure/temperature relief valves.
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
