What is the power draw for a 25 watt low voltage system?
A maximum of 25 watts. On the line side that would be 25w/110 or about 227 milliamps; on the low voltage side, say 12 volts, it would be 25W/12v or 12.5 amps.
How do you calculate battery backup of 12v 7.2Ah output power of 25W?

How many amps do light bulbs draw?
Depend on watt and voltage use of light bulbs. You can use this ohm's law formular to calculate the current draw on light bulbs. I (current in amp) = P (watt)/ E (voltage) If 25W light bulb use in 115V AC (resident home) then current draw will be: 25/115 = 0.22A or 22 miliamperes. Hope this help.
How many watts in 1600 lumen high power led?
25w equivalent
When two bulbes with 25W and 100W rated at 220V are connected in series with a supply of 440V which will fuse?
The 25w bulb, since it has the much higher resistance. The resistance can be derived from:P = V^2/RR = V^2/PFor the 100w bulb:R = 220^2/100 = 484 ohmsFor the 25w bulb:R = 220^2/25 = 1936 ohmsWhen connected in series, and then connected to 440V, the voltage across the 100w bulb would be:V = 440*484/(484+1936) = 88VThis is well within spec.The voltage across the 25w bulb would be:V = 440*1936/(484+1936) = 352vThis is way over spec, and would cause the bulb to fuse.Although this answer assumes that a light bulb is a linear resistor, they are not. The resistance of a light bulb changes significantly with voltage and filiament temperature. The 25w light bulb is still the one that fuses, but the non-linearity of the resistance needs to be understood.

Can a triode tube PET 25W be damaged due to electric fluctuation
Factorize these expression 10-25w?
the answer is 2-5w
Where can you find a freezer light bulb?
u can find it at currys,coment Common appliance bulbs are 25W & readily available lighting section major hardware stores.
Is a rectangle that is 18w by 36L the same as a rectangle that is 25w by 45L?
No!
How much work can a motor with a power output of 25W do in one second?
A power output of 25W for one second is 25 joules. It is also 0.03 horsepower (electric motor scale)
What is the effect of connecting 25 Watts at 110 Volts in series with 100 Watts at 110 Volts?
If you put the 25w behind the 100w then it might not work at the full 25w and vice versa
Which has a higher resistance a 5w lamp bulb or a 25w lamp bulb and how many times?
As per the formula for power (Power (Watt) = Voltage (V) x Current (i) & Resistance (R) = V / i), 25w lamp bulb would have higher resistance compared to that of 5w lamp bulb.
