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.
To properly load the line on a Ryobi 40V string trimmer, follow these steps: Turn off the trimmer and disconnect the power source. Remove the spool cover by pressing the tabs on the sides and pulling it off. Take out the spool and clean any debris or old line. Cut a length of new trimmer line (about 15 feet) and insert one end into the anchor hole on the spool. Wind the line evenly and tightly in the direction indicated on the spool. Leave a few inches of line unwound and insert the other end into the retainer slot. Reassemble the spool and cover, then reconnect the power source. Make sure to consult the trimmer's manual for specific instructions and safety precautions.

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.
