Most likely, yes.
The whole question and answer wasn't provided. An examples is the voltage of the generator is 40V and the resistance of the first device is 12 ohms. To find the current of the first device you would divide 40V by 12 ohms and the answer would be 3.33A.
Impossible to answer without a serial number.

To remove the trimmer head on a Ryobi 40V trimmer, you typically need to press and hold the release button located on the trimmer head while turning the head counterclockwise. This will allow you to detach the head from the trimmer.

Applying turn ratio to a transformer is to step up or step down voltage in an AC system. If you apply a 120V/60Hz (US outlet) to a 3:1 tranformer, you will output a 40V/60Hz signal as the primary side (input) has 3 times the turns (windings) as the secondary (output). From the law of conservation of energy, the secondary side (40V) will now have 3 times the current than the input. 120V x 3A = 360 Watts 40V x 9A = 360 Watts Example: 40V AC Motor with 9A has more torque than a 120V AC Motor with 3 Amps as current is porportional to torque. Voltage is porportional to speed.
The formula you are looking for is Ohms = Volts/Amps. R = E/I.
You may find it helpful to use Ohm's law and the definition of electrical power.
If the form and fit are okay, you are fine since the 40 V is just saying it will operate at a higher voltage.
No, it is not recommended to replace a 40v light bulb with a 25v one. The voltage rating of the bulb should match with the voltage of the electrical circuit to ensure proper operation and prevent damage. Using a bulb with a lower voltage rating can cause it to burn out quickly or potentially create a safety hazard.
5 Ohms Ohm's Law is V=I*R, 40V=8A*R, R=5 ohms.
