If you operate an incandescent light bulb at less than its rated voltage?
Since an incandescent light bulb is an appliance that has a fixed electrical resistance, operating it at less than its rated voltage means that it will draw less than its rated current and will produce less light.
Is 500 watts of AC power is being drawn on an inverter how many amps are being drawn on the batteries powering the inverter?
Inverter efficiencies vary about 50% when a small about of power is being used, to over 90% when the output is approaching the inverters rated output. Your question cannot be answered without knowing the inverters rated output.
What is the BTU output of an electric heater rated at 14.2 kw?
That is 50,000 BTU per hour.
A 100-W light bulb is turned on it has an operating voltage of 120 V how much energy is used each second?
A lamp will only operate at its rated power when subject to its rated voltage. So, provided your lamp is operating at its rated voltage (120 V), it's power will be 100 W, which means its consuming energy at the rate of 100 J/s.At any other voltage, its operating power will change, and the rate at which it consumes energy will change too.
Relationship between current and brightness of a light bulb?
the current is a factor that affects the brightness of the bulb but there are other factors such as if the circuit is in series or parallel. Overall though the current does affect the brightness of the bulbAnswerFor a lamp to operate at its rated power, it must be subject to its rated voltage. It's as simple as that! This is why a lamp's rated power is listed together with its rated voltage on the glass envelope of any lamp. If the voltage is allowed to fall below its rated voltage, then its power output will fall; in fact, a small fall in voltage will result in a proportionally-larger fall in power.
What is rated voltage and current in transformers and how to calculate them if given 50k VA?
Rated voltage is the voltage at primary side. Rated current can be found from the equation, Rated Current= Output KVA / Output rated voltage
How many btu equal a 1 ton heat?
Heating units are not measured in tons as AC units are. Heating capacity is referred to in 1000`s of btu output per hour of operation. The ratio of input vs output = the efficiency rating, for example if your home furnace is rated at 100,000 btu per hour input and 80,000 btu per hour output . it is 80% efficient (when it was new). For AC 12.000 btu = 1 ton.
Why are some heating elements rated for 230 volts and some for 240 volts and what would happen if they are interchanged?
Probably because years ago the voltage supply in most residential applications was 110/220V. It was increased to 120/240V to increase efficiency. If you use a heater element rated at 230V in a 240V application you will be "overvolting" it and will probably reduce the life of the element. If using an element rated at 240V in a 230V application you will be "undervolting" it and it will probably not get quite as warm as it is designed to.
When a light bulb is rated for 3.2 V does that mean that is the maximum operating voltage OR the minimum operating voltage OR or the optimum operating voltage?
When a light bulb is rated for 3.2 V it means that it is the maximum operating voltage to be applied to the bulb.
What is alternator output in amps?
The alternator (or generator) of a vehicle is the unit that converts the mechanical energy from the drive-belt into electricity. Amperage (amps) are the output level of the alternator. Alternator part number, as well as output amps are specific to each vehicle.Another AnswerYour question is a little like asking, "How long is a length of string?"! The rated output current of an alternator depends on its rated output power rating and its rated terminal voltage. The rated output power can vary tremendously, according to the physical size of the machine.
What the output capacity of a motor is rated in?
manpower X3
Power supply units are rated in?
Power supply units are rated based on their output and efficiency. When more equipment is connected, a higher output power supply is needed.
What are the ratings and certificates for Output - 1974?
Output - 1974 is rated/received certificates of: West Germany:16
If you operate an incandescent light bulb at less than its rated voltage?
Since an incandescent light bulb is an appliance that has a fixed electrical resistance, operating it at less than its rated voltage means that it will draw less than its rated current and will produce less light.
How do I find a company that repairs heating units?
In Central Oregon, Ponderosa Heating Repair is the top rated heating repair company. They are very reputable and no doubt will be able to help you with your heating and air conditioning needs.
How are automotive batteries rated?
By Voltage output and capacity in Amp hours.
Why ups rated in kva?
The kva rating includes the power factor of the connected load.KW * Power Factor = kva.AnswerThe above answer is incorrect, as it's actually kV.A x power factor = kW.The answer is straightforward, the output of the UPS is the product of its rated output voltage and its rated output current, and the product of voltage and current is 'apparent power', expressed in volt amperes.
