Power is a quantity, and the watt is its unit of measurement.
Volt-amp is a unit of apparent power, which is the combination of voltage and current in an electrical circuit. Watt, on the other hand, is a unit of real power, which is the actual power consumed by a device. The relationship between volt-amp and watt is that watt is the product of volt-amp and power factor, which represents the efficiency of the electrical system. In simple terms, watt is the actual power used by a device, while volt-amp is the total power flowing through the circuit.
The main difference between a 100-watt and a 75-watt light bulb is the amount of light output they produce. A 100-watt bulb will be brighter and consume more energy compared to a 75-watt bulb. The 100-watt bulb may also generate more heat than the 75-watt bulb.
A "watt" is a derived unit of power.
An amp (ampere) is a unit of electric current, measuring the rate of flow of electricity in a circuit, while a watt is a unit of power, quantifying the rate at which energy is transferred or used. In simple terms, amps measure the amount of electricity flowing, while watts measure the amount of power being consumed or produced.
A voltamp is a unit of apparent power, which is the combination of voltage and current in an electrical circuit. A watt, on the other hand, is a unit of real power, which is the actual power consumed by a device. The relationship between voltamps and watts is that in an ideal circuit with no reactive components, the apparent power (voltamps) is equal to the real power (watts). However, in real-world circuits with reactive components like inductors and capacitors, the apparent power can be greater than the real power due to the presence of reactive power.
The difference is in the output frequency.
power difference
No difference in case of DC. In case of AC Watt refers to Power which includes the factor of power factor. VA does not include power factor.
The main difference between 35 watt and 50 watt HID lights is the power consumption and light output. A 50 watt HID light will consume more power and produce brighter light compared to a 35 watt HID light. The choice between the two would depend on the specific lighting needs and preferences.
The difference between a 60 watt and a 100 watt bulb is the amount of power each consumes and the brightness they produce. A 100 watt bulb consumes more energy and therefore produces more light than a 60 watt bulb. This can impact the brightness and energy efficiency of the lighting.
The Watt is the unit of Power, where power is the rate of change or transfer of energy and equals 1 Joule/second.

Both are used to measure power. The horsepower is simply the Imperial unit for power, whereas the watt is the SI unit for power, where one horsepower is equivalent to 746 watts.In North America, it is traditional to measure the output power of an electric motor in horsepower, while the watt is used to measure its input power. Elsewhere in the world, the watt is used to measure both input power and output power. (The difference between output power and the input power is due to losses, such as heat transfer, friction, windage [air resistance], etc.)Outside North America, the output power of a car engine is now measured in kilowatts rather than in horsepower.
Those numbers describe the power used by the two bulbs, in other words how many joules of electrical energy they use per second. The 100 watt bulb uses 40 watts more.
Increase = 10 log(B/A) dB = 10 log (3000/1) = 10 ( 3.47712) = 34.8 dB (rounded)

Using 100 watts for 2 hours consumes a total of 200 watt-hours, while using 50 watts for 4 hours consumes the same 200 watt-hours. The difference lies in the power output over time: the 100-watt appliance will consume power more quickly compared to the 50-watt appliance, but they both consume the same total energy.
