Why do you think as the voltage across a lamp changes the power consumption?

Because the power of a resistive component is directly proportional to the square of the voltage across that component.

How much would you choice for amperes at 2750 kw and 11000v for power consumption?
Power = Voltage * Current Current = Power/Voltage, = 2,750,000/110,000 = 25 amps.
What is the formula for bjt power consumption?
it is the collector voltage multiplied by the sum of all the currents.
How do you figure out an appliance's power consumption if you have the voltage and Frequency and Current?
You just need the voltage and the current. Watts = Amps x Volts.
What is power regulator?
A power regulator or a voltage regulator generates a fixed output voltage of a preset magnitude that remains constant regardless of changes to its input voltage or load conditions.
How do you calculate electrical power?
Voltage x current. In a resistor for example it is the voltage drop across it that is relevant, it may be part of a circuit.
How does changing voltage across a lamp affect the power consumption of the lamp?
because it does!
How much power is consumed by a load drawing 5 A with 12 V across it?
Power = Voltage x Current. So it will be 60W of power consumption, in your case.
What happens when lagging Power Factor changes to leading PF?
when lagging Power Factor changes to leading PF, then the voltage across the circuit in which capacitor bank is connected, is increased.

You just need the voltage and the current. Watts = Amps x Volts.
A voltage spike is another term for power spike?
Only if there's a 'load' across the voltage.
How to calculate power consumption by induction melting furnace?
simply by measuring the coil voltage, coil current & power factor.
How can you categorize projects into high or low voltage projects?
You can categorize the projects into either low or high voltage projects based on the power consumption.
What is the difference between voltage drop and power loss?
voltage drop is the loss or drop that occured across the element so that voltage gets down and current increases across the element and power loss is like i2r loss and like wastage of power without consuming
Does voltage add in a series circuit?
The voltage between the ends of the circuit doesn't change ... that's where the power source is connected. But when you add more items in a series circuit, the voltage across each item changes. The individual voltages across each item in the series circuit always add up to the voltage of the power source. So in general, if you add more items, the voltage across each of the original ones must drop somewhat.
How do you calculation power in a transformer?
In an ideal xmfr, the power in equals power out and only the voltage and current changes.
