Normally that would be however many volts your house runs on. The US/Canada standard is 120 volts at 60 hertz, while most of Europe runs on 240 volts at 50 hertz. Keep in mind though there are all types of light bulbs that run on all voltages from 12 to 240. It should say the voltage on the bulb though? but if you live in North America and you are asking about a normal house-type bulb, your quest will most likely end with 120.
You can't calculate how many volts with that information; you could calculate the energy - 60 watts for 15 minutes is equivalent to 54,000 joules.
Onions don't have volts.
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 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.
A 65 Watt incandescent light bulb should draw 65W/120V = 541.67mA

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.
To answer this question the voltage of the bulb is needed.
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.
