When do you need to convert the voltage for appliances?
You need to convert the voltage if your appliance requires less voltage than you power supply. example: appliances is 110V and power supply is 220V.
What effect will a transformer have on alternating current?
A transformer will convert the power to a different voltage, higher or lower depending on the requirement, while wasting very little of the power.
If voltage is 127v does this use more kilowatts than if voltage were lower?
...maybe...The black and white answer is "yes". It becomes much more grey when you're question evolves into "how much more". It depends on what you're using whether this will really make a difference. A higher voltage into a light bulb will cause more current to flow, thus a higher power usage. A higher voltage into a computer will not increase power usage by much, because the internal electronics convert this into DC that is clamped to specific values (12 volts, 3.3 volts, etc.), and the parts of the computer function on this lowered voltage. There will be a larger amount of loss in the power supply. A heater will heat more at a higher power usage than at a lower power, so voltage being higher is irrelevant - it will simply run longer and cooler at lower voltage than at higher voltage.
How do you convert 110volts to kVA?
You must know the current or resistance to convert voltage to power.
Does centre tap transformer convert ac voltage to ac voltage?
Yes. Transformers convert power by stepping up or down voltage. It doesn't matter what tap configuration they have.
How do you convert arms to watts?
To convert arms (root mean square current) to watts (power), you need to know the voltage in the circuit. The formula for this conversion is: Power (W) = Current (Arms) x Voltage. Multiply the root mean square current (Arms) by the voltage in the circuit to get the power in watts.
Why do electrical power companies transform higher voltage to lower voltage for residential and commercial properties?
Because the higher voltage would be dangerous domestically.
What is power cable size for 1 kw 1 phase motor over 500 meters?
It depends on the voltage that the motor needs, because a higher voltage requires less current for a given amount of power. Also a higher voltage can tolerate a higher voltage drop. So there are two things that lead to a thinner wire when the voltage is higher.
What are the adverse effects of poor power factor?
Low power factor means higher than necessary load currents. These require unnecessary expenditure on the amount of copper in supply equipment such as cables, transformers, and switchgear. Higher than necessary load currents also mean greater voltage drops and poorer voltage regulation.
Function of power supply?
to convert AC into DC voltage without fluctuation
When ac convert in dc then voltage will increase or decrease?
You can make it so it does either increase or decrease. The limiting factor is that power out cannot exceed power in. So going to a higher voltage will limit current and going to a lower voltage will increase current available. A2 Because AC is continuously changing in a sinusoidal waveform, it is hard to determine the exact voltage. It is usually called by it's RMS value (Root Mean Squared). The result is that when you fully rectify an AC voltage, the DC voltage is actually HIGHER than the RMS AC voltage.
How to convert 120v to 240v for electrical appliances?
To convert 120v to 240v for electrical appliances, you can use a step-up transformer. This device increases the voltage from 120v to 240v, allowing you to safely power appliances that require the higher voltage. Make sure to follow all safety precautions and consult a professional if needed.
