# approximately how long will it take for 171v to drop to 100v with a 75w light bulb? [closed]

I'm not an electrical engineer, but I do have a question regarding voltage and timing.

Approximately how long will it take for 171v to drop to 100v with a 75w light bulb?

Im only looking to figure out how long it would take to discharge a battery.

The battery I am discharging is a 2005 Honda Accord Hybrid IMA 144V Nickel-Metal Hydride battery.

6.0 Ah

• Similar question: approximately how far can you get on a full tank with a car which has a top speed of 144 km/h that uses 75 liters per km? Mar 10, 2018 at 20:09
• The similarity here is that there's no datasheet, no information about the size of the fuel tank, Ah (Ampere hours) in your case. It's one parameter that is missing that is needed to solve this simple puzzle. Mar 10, 2018 at 20:14
• This question is not very hard to answer, but just like other bad questions, it indicates some very bad design. Mar 10, 2018 at 20:24
• you indicated that you have the battery. ... get a stopwatch, a voltmeter and a 75W lightbulb and do the experiment yourself ... why are you even asking your question? Mar 10, 2018 at 20:27
• Use a DMM ammeter and count Ah Mar 10, 2018 at 20:57
