Given:

Bite Force of T. rex: 45,000 Newtons

Jaw Closing Distance: Approximately 0.3 meters

Energy=Force×Distance=45,000N×0.3m=13,500Joules

Say we have a typical 10w led lightbulb, how much could it power it for?

Time= Power/Energy=13,500J / 10W=1,350 seconds, or approximately 22 and a half minutes with a single T-Rex chomp, assuming 100% conversion efficiency

Fun fact, the (rough) conversion efficiency of calories to mechanical joules in the human body (separate from the mechanical to electrical you're referring to) is about 25%

but this is about the same factor as going from calories to joules! So, for a human to put out 13.5 kJ of energy would require about 13.5 food calories (kilocalories).
