Which is the best example of potential energy? Potential energy is the stored energy an object has because of its position or state. A bicycle on top of a hill, a book held over your head, and a stretched spring all have potential energy. What are two examples of kinetic and potential energy? What Are […]
How high can a helium balloon go?
How high can a helium balloon go? 9,000 meters What happens to a helium balloon in space? One is that atmospheric pressure is dramatically reduced at high altitudes, so a helium balloon expands as it rises and eventually explodes.

Can a load be a resistor?
Can a load be a resistor? Devices called resistors are built to provide precise amounts of resistance in electric circuits. Any device that performs some useful task with electric power is generally known as a load. Sometimes resistor symbols are used in schematic diagrams to designate a non-specific load, rather than an actual resistor. What […]
