# 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? – Harry Svensson Mar 10 '18 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. – Harry Svensson Mar 10 '18 at 20:14
• This question is not very hard to answer, but just like other bad questions, it indicates some very bad design. – user3528438 Mar 10 '18 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? – jsotola Mar 10 '18 at 20:27
• Use a DMM ammeter and count Ah – Tony Stewart Sunnyskyguy EE75 Mar 10 '18 at 20:57
