A light bulb which is 20Watts, is run for 2 hours, which equals to 40Wh.
This means 40Watts are used in an hour.
Does that kinda make sense?
An actual definition is:
Wh - Watt-hour, measurement of the total energy of the battery.
Hope this helped! :]
What else can I help you with?
48 Wh vs. 56 Wh battery?
the 56 wh has a higher capacity and will last about 30 mins longer.
What does 56Wh mean on dell lap top battery?
Wh means Watt-Hour. It indicates how long your battery will last. The higher the Wh, the longer your battery will last.
What does 85 Wh mean?
The letters Wh means watt hours. this is how many hours of power the battery can store. The larger the number, the more power the battery can store. This is important for laptops, smartphones, and tablets. or Another way to measure the capacity of the battery is in watt-hours(wh). wh is calculated by multiplying the number of Amps with the battery voltage.
How much 5.70 wH battery has in mA?
1500mAh
How much electrical energy is supplied by the battery?
The amount of electrical energy supplied by the battery is measured in units called watt-hours (Wh). This value can vary depending on the capacity of the battery, which is typically listed in milliampere-hours (mAh) or watt-hours (Wh).
Is 4800mAh is equivalent to 56 Wh?
Only if the battery is rated at 11.66V. mAh / 1000 => Ah (4800 mAh = 4.8 Ah) Ah * V => Wh (4.8 Ah * 11.66 V = 55.97 Wh)
What is the cost of 12volt 500Ah battery?
On the Internet I saw a NiMH battery 12V 50 Wh for about $50 USD so ten times that $500
How does 21.6 Wh compare to 4400mAh?
To compare 21.6 watt-hours (Wh) to 4400 milliamp-hours (mAh), you need to know the voltage of the battery. Watt-hours is a measure of energy, while milliamp-hours is a measure of electric charge. If you assume a common lithium-ion battery voltage of 3.7 volts, you can convert 4400 mAh to watt-hours using the formula: Wh = (mAh × V) / 1000. This would yield approximately 16.28 Wh, which means 21.6 Wh is greater than 4400 mAh at 3.7 V.
What does V and WH stand for in battery language?
John Morganti gave this explanation of "Wh": The watt-hour (symbolized Wh) is a unit of energy equivalent to one watt (1 W) ofpower expended for one hour (1 h) of time. The watt-hour is not a standard unit in any formal system, but it is commonly used in electrical applications. The designation 5 Wh indicates that the battery will power a load of 1 watt for 5 hours or a load of 5 watts for 1 hour.
How much is 56Wh in MAH?
Answer #1:56watt = 56000mw,1000milliamp = 1amp,watt = amp x volt = watt/volt,if the battery is rated 11.1v,so 56000mw/11.1v = 5 045.04505mah==============================Answer #2:Answer #1 has a big ' if ' hidden in it.In general, 56 Wh = 56,000/voltage of the battery mAh and for ANY number of Wh ... call it ' P ' ...P Wh = 1,000 P/battery voltage mAh .
What if a battery is rated at 76 wh and should be rated at 90 wh?
I don't understand the question. Batteries are rated at their watt-hour rating. This means the amount of energy the battery can delivery. However, these ratings are often exaggerated and in any event they are based on a specific use current -- other currents will change the actual watt-hours.
How much energy is stored in a battery?
The amount of energy stored in a battery depends on its capacity, typically measured in watt-hours (Wh) or joules (J). For example, a battery with a capacity of 100 Wh can store 100 watt-hours of energy. The energy stored in a battery can be calculated by multiplying the voltage (V) of the battery by its capacity (in amp-hours, Ah).
