Answer :
A lamp receives a 3 a current for 2 seconds from a 6 v power source. This lamp lost 3.6J of energy during those two seconds.
J=0.3 A
t = 2MIN = 2*60 =120sec
V=6v
E=VIT
=6*0.3*120
=216J
for 2 sec is
E=VIT
=6*0.3*2
=3.6J
Energy is characterized as having the "ability to accomplish work, which is the capacity to apply a force sufficient to move an object." Despite this unclear definition, the concept is actually quite straightforward: energy is just the force that moves objects. Potential and kinetic energy are the two different categories. An electrical charge carrier flow known as current often involves electrons or atoms lacking in electrons. Amperes are the common unit and are denoted by the letter A. Typically, the letter I is used to represent current. While current and electron flow in the same direction, they do so in opposite directions. Electrons move from a negative potential to a positive potential, and vice versa.
