How much total energy is dissipated in 10. seconds
in a 4.0-ohm resistor with a current of
0.50 ampere?
(1) 2.5 j (3) 10. j
(2) 5.0 j (4) 20. j

3) 10 J

Explanation:

Electrical energy dissipated is given as

here we know that

i = electrical current = 0.50 A

R = 4 ohm

T = 10 s

so we have electrical energy given as

i guess it’s a and b

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
