Two hundred joules of energy are consumed in 10 s What is the power?
Simply divide energy by the time. Answer is in Watts.
What 4.5 watts equal?
It is equal to 4.5 joules per second. "Watt" means how quickly energy is generated, consumed, or converted.
When a light bulb is rated at 60 watts it means it?
. . runs at a constant 60 watts of electric power. In an hour it uses up 60 watt-hours of energy.
Will a 30 watt transformer damage a device needing only 15 watts?
No, the rating of the transformer, in watts, is the maximum amount of energy that can be safely drawn from the device. Any wattage load up to that limit is safe to connect as long as the voltage is correct to the load.
How many watts does a 15volt 6amp ac?
if the question is how many watts consumed then under normal circumstaces 15volts time 6amps will give you 90 watts.
Why are generators rated in watts?
Generators are rated in watts because watts are the scale on which energy is measured.
How do you found out which watts is using the most energy?
Watts is a unit of power, energy / time. Therefore, the energy consumption of a device is the amount of watts, multiplied by the time the device is turned on.
Two hundred joules of energy are consumed in 10 s What is the power?
Simply divide energy by the time. Answer is in Watts.
Could you get the watts for certain sockets?
Yes, very easily. Receptacles and other electrical devices are rated in amperage that the device can use or handle. Take that amperage and multiply it by the voltage that the device is rated for. The answer will be in watts. This wattage will be the maximum that is allowed from the receptacle or any other device.
What gets used up in an electric circuit current or energy?
One of Kierchieff's laws tell us that the more wattage (energy) consumed by an electrical device in a circuit, the larger the voltage difference that exists across the device and the greater the current flowing through it. The energy consumed is directly proportional to the Impedance of the electrical device but is more importantly proportional to the square of the current. WATTS=VOLTS X AMPERES= RESISTANCE (IMPEDANCE) X AMPERES X AMPERES A Circuit with Current but without resistance would exhibit no energy at all.
If current is 4amp and voltage is 240volts what will be the energy consumed in one hour?
The formula for watts is W = I x E. Watts = Amps x Volts.
How many Watts are consumed by computer monitors?
A modern LCD screen in sleep mode consumes less than 2 watts. When in use, my 19" device consumes 150 watts according to the tag on the back.
How much energy does a blow dryer take?
They come in different sizes, and power ratings. Look at your dryer; somewhere it should have electrical specifications. These should either include a power (in watts), or volts and amperes separately. If volts and amperes are listed separately, multiplying them gives you a good idea of the amount of watts consumed. Note: watt is a unit of power, not of energy. You need to multiply that by the time you use the device, to get energy: joules = watts x seconds
What is the power?
Power in electricity is the rate at which electrical energy(E) is produced or consumed in a given time(t). Is measured in watts(W).
What 4.5 watts equal?
It is equal to 4.5 joules per second. "Watt" means how quickly energy is generated, consumed, or converted.
How much energy do you need for 1 power saving light In kWs?
A power saving light is also known as a Compact Fluorescent Lamp (CFL).A typical CFL is rated at about nine (9) to thirteen (13) Watts, and the energy consumed by each is 0.009 kW and 0.013 kW respectively.
What are Electrical devices are rated in according to the amount of energy per second that they need to operate?
watts
