How do you find the actual wattage of an electrial component?
Wattage= current*voltage*power factor. Wattage=VI Cos(@)
How can you the actualk wattage for each components on a computer?
You can go to the manufacturers website for each component to find the exac wattage amounts. Or if not available you can go to http://www.pcpower.com/technology/power_usage/ and get the estimate provided or the midpoint of the estimate.
What is the Formula you can use to find the capacity of a laptop battery?
Wattage = Outage Voltage + Outage Wattage
How do you find watts for my microwave if you don't have your manual for it?
Open the door and look for a label that lists all of the important details on the door frame It should list input and output wattage - the input wattage is how much power it draws, and the output wattage is the actual cooking power. Some brands may have this label on the back, but it's usually inside the door.
Have lincoln wire welder 115v 15a how many watt generator to operate?
To find the wattage needed , you multiply amps by volts. In the case of a portable generator you need to find the running wattage. most generators display peak wattage in large numbers on the top , or frame . this is not suitable for welders, which may exceed this for longer than the gen. is rated . You need to look at the actual tag that shows running watts and specific voltages.
What would be the maximum rating of the incandescent bulb for a dimmer switch?
Find the wattage rating on the dimmer controller. This is the maximum allowable wattage that the lamp in the fixture should be. Lamp wattage ratings under the rated dimmer wattage is fine but do not install a larger wattage lamp that is over the dimmer control's rating.
Why is it better to use low wattage appliances?
Every electrical item draws a certain number of watts, the given unit for measuring energy consumption. If you are trying to determine how much wattage your house will pull over any period, you'll need to find out the wattage of each appliance. Each appliance can have wildly ranging wattages depending on the model, features and manufacturer, so the numbers listed here are just approximations from the U.S. Department of Energy
Do you konow about vector integration?
yep, integrate each component seperately, but remember there will be a constant of integration for each component that you integrate. You can find the value of these constants if you have some initial conditions, otherwise just leave them as arbitrary constants, though in practice most problems will have conditions that allow you to find the values of the constants.
What formula can be used to find wattage?
Watts= Volts x Amps
What wattage 12 volt inverter do you need to drive a 240 volt quarter horsepower pump motor?
You need to find the wattage of the pump motor. This is found by multiplying the voltage of the motor by the amperage of the motor. Once you have this figure use it to find an inverter that can handle this wattage load at a 240 volt output.
How do you find the wattage of a microwave?
It is printed on the label and may also appear on the front.
How can you connected two heating elements each having 1000 watts to get lowest heating?
Connect the two heaters in series. The supply voltage, what ever the value, will be split in half across the two heaters. If the voltage is dropped by half across the two heaters in series, the wattage of each heater will be dropped to one quarter of the heaters wattage rating at its full voltage rating. The new wattage's will be added together for a new total wattage for the circuit. When you find the heaters working voltage use these two formulas; This one to find the resistance of the heater at its working voltage value, R = E (squared)/Watts. Then to find the watts at the reduced voltage value, W = E (squared)/R. R being the heaters resistance in ohms from the first formula.
