Alight bulb converts electrical energy into light energy and also some thermal energy.  the amount of electrical energy is 50 joules before the conversions.   what is the total amount of energy after the conversion?     question 5 options: 100 joules because you start with one form of energy and end up with two forms, so the amount of energy doubles. 45 joules because some energy is lost when it is put off as heat. 55 joules because as more electricity comes in to the light bulb, the joules increase. 50 joules because as energy converts from one form to another, it cannot be created or destroyed during the conversion.
