What are nominal values?
Nominal values are the values that a component is specified to be. For example, the nominal value of a 10K resistor is 10K. Its actual value may vary, though, based on its tolerance.
Why prefer nominal pi circuit over nominal T circuit in transmission line modeling?
Nominal Pi is used for the transmission line modeling as it makes the Y matrix representation more accurately and in actual sense we get a conditioned matrix.
What is the function of the tolerance band on a fixed resistor?
A: Not all application need close tolerance of values some application only need 5% and some 10% so the band is there to specify the -/+ % tolerance that the part is in compliance with. Designers decide what parts % is needed for proper performance of the circuit.
Can you install a 120V baseboard heater on 110 amp power service?
Yes. The voltage of 120 volts is a nominal figure. The utility company has a plus or minus tolerance from 110 to 120 volts. This tolerance is based on the figure of 115 volts.
Is it legal to have a 220 volt branch circuit?
The answer will depend on where in the world you live and the local adopted electrical code. In the US, generally yes, 220V branch circuits are legal. Most electric ranges, electric water heaters and house air conditioning units require 220 (actually nominal 240) volts, and are fed from a branch circuit. There are limitations and exceptions. For instance, the NEC ( 210.6(A) ) limits the following branch circuits to 120 volts nominal: In dwelling units, guest rooms or guest suites of hotels, motels and similar occupancies, the voltage shall not exceed 120 volts, nominal, between conductors that supply the terminals of the following: 1. Luminaires (lighting fixtures) 2. cord-and-plug connected loads 1440 volt-amperes, nominal, or less or less than 1/4hp. NEC (2005) article 210.6 covers branch circuit voltage limitations.
Is 24.0 mfd a good test reading for a 24.5 mfd run capacitor with a multimeter?
That would depend on the tolerance of the capacitor. As the measured value is only about 2% below nominal and most capacitors have 10% or 20% tolerance it should be fine. However if it was a precision capacitor with for example 1% tolerance it would be bad.
Interpret the system of tolerancing?
Engineering drawings come with a set tolerance, a value or allowance from nominal. This will be either dimensional or geometric. It is a set size that can be unilateral or bilateral from the nominal for example (+/- 0.25) or (+0.1-0) this can cover the whole job but often it will be individual features like run-out, ovality, diameters and lengths.
What is the roundness tolerance for schedule 40 pipe?
The allowable deviation of diameter (schedule 20 and greater) at any point from nominal diameter is: Under 2": +.015/-.031 2"-12": +/-1%
Can you use a 125 volt bulb in a 120 volt lamp?
Yes, the voltage listed on the bulb is the nominal voltage and it will work perfectly on a 120 volt circuit.
What is the nominal zone circuit voltage in an Addressable Fire Alarm System?
When we discuss fire panels and "nominal" voltage on a circuit we must first determine what type of circuit. Addressable panels can have varied circuits that all perform different funtions. The two most common are Notification Appliance Circuits (NAC), and Signaling Line Circuits (SLC). "Nominal" should be replaced by different terms. "Monitoring voltage", and "Active Voltage" to be substituted for NAC circuits, and "intializing voltage" and "polling voltage" for SLC circuits. Monitoring voltage for NAC circuits vary, however it commonly either between 2-4vdc, or -24vdc. Once a NAC circuit is activated "active voltage" it is almost always 24vdc. "Intializing voltage" on a SLC circuit is caused when a circuit is first plugged into its associated board and the voltage "spikes" to 24vdc then settles at its "polling voltage" at either 24vdc or between 12-18vdc.
