Answer 1

Answer:

we know that

power= energy/time

so

we will find the power first

we know that power = V²/R

so now we will find the Reff.

as they are connected in series then effective resistance= 3+6 = 9ohm.

so now power = 12²/9 = 16.

so power = work done(energy) / time

hence energy= 16× 60. = 960jule
