Small bulbs come in many different voltages. It will always be marked on the bulb and will only work correctly with that proper voltage applied.
Onions don't have volts.
If a light bulb is rated at 60 Watts, the voltage will depend on the specific type of bulb. For a typical incandescent bulb, the voltage would be around 120 volts. However, for an LED or CFL bulb, the voltage could be different, such as 120 volts or 240 volts.
Each light bulb will receive the full 9 volts from the battery in a series circuit, so each bulb will be operating on 9 volts.
15.
A fluorescent light bulb typically operates on a voltage range of 100-277 volts, depending on the specific model and design. The most common standard voltage for residential use in the United States is 120 volts.
amps equals watts divided by volts.
.63 ampere draw @ 7 volts
A typical big light bulb, like an incandescent bulb, usually requires around 120 volts to operate. However, it's always best to check the specific voltage requirements listed on the bulb itself or its packaging to ensure safe and proper operation.
The amps drawn by a 65 watt light bulb should be 65/120 or 0.54167. This fraction of an ampere may be restated as 541.67 milli-amps.
If you divide the watts of the bulb by the supply voltage, that is the current. For example a 60 w bulb on a 240 v supply gives a current of 60/240 which is ¼ amp.
Most household lamps in the US use either 120 volts or 240 volts, depending on the wiring system in the building. It's important to check the lamp's specifications and the voltage in your home to ensure compatibility and safety.
A 65 Watt incandescent light bulb should draw 65W/120V = 541.67mA
