Separate devices should always be hooked up in parallel, and not series. Therefore, you would combine the total current requirement, which in this case is 600mA or 0.6A. You would therefore need a 9V power supply that is capable supplying at least 0.6A.
It depends on whether the devices are connected in series or parallel or some combination of the two.
The current in a series circuit is the same throughout the circuit. The current in a parallel circuit is the sum of the current in each parallel branch
If the three devices are connected in series, the required current is 200mA.
If the three devices are connected in parallel, the required current is 600mA
The total power required by a circuit is the sum of the power consumed by each component. It doesn't matter if the devices are connected in series or parallel. Power = voltage x current.
If the three devices are in series, the power consumed by one of them is 9 x .2 = 1.8 watts. The total power consumed is 1.8 x 3 = 5.4W
If the three devices are connected in parallel, the power consumed is 9 x .6 = 5.4W
Notice that the power consumed is the same for the series and parallel combination. The battery (or power supply) must be able to supply 5.4 watts.
You can power any amount of devices that total to a sum of 3000 watts. If you can not find the wattage on the devices nameplates then use the amperage of the devices. I = W/E Amps = Watts/Volts. 3000/120 = 25 amps. A total of 25 amps can be used from a 3000 watt generator.
You can power any amount of devices that total to a sum of 800 watts. If you can not find the wattage on the devices nameplates then use the amperage of the devices. I = W/E, Amps = Watts/Volts. 800/120 = 6.6 amps. A total of 6.6 amps can be used from a 800 watt generator.
You can power any amount of devices that total to a sum of 3250 watts. If you can not find the wattage on the devices nameplates then use the amperage of the devices. I = W/E Amps = Watts/Volts. 3250/120 = 27 amps. A total of 27 amps can be used from a 3250 watt generator.
You simply add the power of each phase together to determine the total power.
Total voltage that you use in your home is constant. For Europe ~230V, for US ~120V. But the total power that you use differs and depends on total power consumption of the devices you use [Watt/h].
the power of the ocular lens multiplied by the magnification of the objective lens
Total takings/number of guest = mean average
Learn the power consumption of devices, they hours of operation and cost of power. Use this information to work out e.g. total power usage / year and cost / year.
how do calculate total of rooms revenue
In the context of data centers, PUE stands for Power Usage Effectiveness. It is a measure of the total facility power consumption in relation to the power needed to run strictly IT equipment. To calculate PUE, you take the total facility power draw and divide it by the IT load. The average PUE is generally believed to be 2.0, meaning an IT load (servers, storage, etc.) of 10 kW requires an additional 10kW of power to keep cool, run lights, and electricity lost through the inefficiencies of the power system.
Watts is the product of amps x volts. Add up all of your connected loads and that will be your total watts that are needed for the power supply to produce.
Either (1) determine the power of each branch, and add them together, or (2) multiply the load current by the supply voltage.
To figure out the quantity of concrete, you will need to calculate the total length, width and depth in inches. There are online calculators available which can easily compute the total amount needed.
By calculating the total power required by all the electrical appliances.
a 15 amp circuit breaker means you can use devices upto 7.5 amp calculate total current used by this devices and make sure they dont cross a sum of 7.5 amps
You need to calculate the total volume of the space that the concrete has to fill. if you're doing a slab 4" thick a cu. yd. will cover 81 sq. ft. Take the total area and divide by 81 to get the number of yard needed.
you calculate average speed by dividing the total distance to the total time.

calculate the total sum of lighting power and add 10% as safe operation of the transformer. then select a transformer for that rating. suppose your total lighting power is 300VA. add 10% of the total lighting power so the total power is 330VA. therefore your transformer size can be 330va or more. please follow IEE regulations.
Make two lists. List the appliances you want the generator to run when commercial power is available. Next, list the appliances you want the generator to run when commercial power is NOT available. Determine the wattage of each appliance and then add them together for the first list. Repeat this for the second list. This will give you total wattage for each list. This will help you determine the size of the generator needed to power your devices when commercial power is available and for when commercial power is not available.Understanding the wattage values of each appliance is important for correctly choosing the wattage values to add together to get the total estimated wattage needed to power your appliances.If all of your loads are resistive, such as incandescent lamps and heaters, you simply add up their wattage to get a total. However if you have electric motors which will cycle on and off or appliances like a heat pump or an air conditioner, you must take into consideration the required starting current of these devices. The start up current of these devices can be up to 6 times the running current.Starting Watts are the power the generator can produce for short periods of time.Running Watts are the power the generator can produce continuously.Here is an example of how to determine generator size:Question: I am considering the purchase of a standby portable generator to power key appliances in the event of a power loss which sometimes occur during winter snow storms. Do I just add up the total number of watts required by the appliances I want to run? In the event of a winter storm interruption of electricity, I am looking to keep the refrigerator/freezer running, along with the blower motor of a pellet stove, a few electric lights, and a radio. All else can wait until power is restored!Answer: The total estimated wattage of 1840 watts is needed for the radio (15 watts), the motor (575 watts), and the refrigerator/freezer (1250 watts). To this I added 500 watts for five 100 watt light bulbs for a total of 2340 running watts. Next I added the starting watts of the motor to the running watt total of 2340 watts, to get the total estimated wattage of the generator needed to power all these appliances simultaneously. For example, assuming the starting watts needed for the blower motor are 3 times its running watts (3 times 575 watts = 1725 watts), so the total estimated wattage of the generator needed to power all these appliances simultaneously is 2340 running watts plus the 1725 starting watts of the blower motor, for a total of 4065 watts. The generator needed to run all these appliances simultaneously would need to have a maximum power output of at least 4065 watts.Note: The maximum power output is also called short time watts, peak watts, maximum watts, surge watts, and starting watts. It's helpful to keep this in mind when reading portable generator wattage ratings.
