Very few bulbs take exactly the nominal power. Because of manufacturing variations they can take up to 5% less or more than stated. It could also be due to measurement inaccuracy in the measuring equipment used for this measurement.

What is actual power being used in an electrical circuit?

Actual power, often referred to as real power or active power, is the power consumed by electrical devices to perform useful work in a circuit. It is measured in watts (W) and represents the energy converted into work, heat, or light. Actual power is calculated using the formula ( P = VI \cos(\phi) ), where ( V ) is the voltage, ( I ) is the current, and ( \cos(\phi) ) is the power factor, which accounts for the phase difference between voltage and current in AC circuits. Unlike apparent power, actual power reflects only the portion of energy that contributes to productive work.


When using a microscope how much larger than normal does an object appear with lower power objective?

Not all microscopes have the same magnification for the lower power lens.


What are the reasons for always starting on low power for microscope?

The higher the power, the more difficult it is to have the item being viewed centered in the viewing field. However at lower power the viewing angle is wider and it is easier to find and position the item in the field. So we start by centering the item in the field at lower power, increase the power and center it again.


What is apparant power?

Apparent power is the combination of real power (which is the actual power consumed by a device) and reactive power (which is the power oscillating between the device and the source due to the load's inductance or capacitance). It is measured in volt-amperes (VA) and represents the total power flowing in an alternating current circuit.


What is the power consumption of LED monitors?

The power consumption of LED monitors is generally lower compared to other types of monitors, typically ranging from 15 to 30 watts.

Can 150 volt amp output handle a 100 watt bulb?

Yes it can provided the volotage is right, because for a bulb the volt-amps are equal to the watts - if it is an incandesent bulb. For a fluoresecent bulb the power-factor must be better than 100/150 or 0.67.

Why is lower power dissipation better?

the lower you can get your power dissapation means the less heat the electronic piece will have to give off. the lower it is, the more efficient the system is. the lower you can get your power dissapation means the less heat the electronic piece will have to give off. the lower it is, the more efficient the system is.
