Temperature SystemHow and why do we control heat on a spacecraft? |
A resistor is anything that electricity can not travel through easily. When electricity is forced through a resistor, often the energy in the electricity is changed into another form of energy, such as light or heat. The reason a light bulb glows is that electricity is forced through tungsten, which is a resistor. The energy is released as light and heat.
A conductor is the opposite of a resistor. Electricity travels easily and efficiently through a conductor, with almost no other energy released as it passes.
A resistor placed at the exterior of a spacecraft can release extra electrical energy into space as heat.
