Does Fiji use water power?
Fiji's natural resources are timber,fish,gold,copper,off shore oil penitential and hydro power too.
What power is used in Fiji?
Fiji has the same power connections for electrical appliances as does Australia and New Zealand
Why you use transformers to transfer power?
Transformers do not exactly transfer power, they either step up voltage or step down the voltage from one source to another to make it a useable voltage.
Can you calculate power by multiplying voltage and current?
Not enough information. Power = current x voltage. Since voltage can be anything, there is no way to calculate power. Time is irrelevant; though once you have the power, it can help you calculate energy (energy = power x time).
What is use of substaion near grid station?
A power substation is used to reduce the voltage from high voltage power lines to a voltage that is less dangerous that you can use in a house for example. It is less costly to transmit electrical energy over long distances using high voltage.
What is the safest voltage to use power tools in a workshop?
Do you have a choice ? All my power tools are 110 volt, so that is what I use.
How do yo calculate electric power and energy use?
Power = voltage x current Number of power in volts
When using power tools in the workshop what is the safestbest voltage to use?
110
How can you calculate the current an appliance can use?
current=watts(power)/voltage
What law would you use to determine the voltage of a power supply?
ohms
How many DC volts of solar power would it take to suppy a home 3500kWh?
Power = voltage * current. Without current, relating voltage to power is meaningless. One thing I can say is the voltage should be dictated by the amount of losses that is acceptable - the cabling you use to transfer the power to your home will have a specific resistance per unit length, which is unchanging. If you choose to use a low voltage, you will in turn use a fairly high current to transfer the energy you want. The power lost in the cable will be P = R * I^2. This loss can become significant, dictating a higher voltage.
How much voltage does an electric iron takes?
Electrical devices are built to work with the voltage in your home. All electrical devices use the same voltage, which is either somewhere around 110 V (in some regions) or somewhere around 220 V (in others). Please note that "voltage" is not the same "power", the measure of how fast energy is used. Power (in watts) is basically the product of voltage (in volts) and current (in amperes). Different devices use the same voltage; but devices that use a lot of power (such as electric irons, or showers) use more current.
