When the metal wire in an incandescent lightbulb glows when the light is switched on and stops glowing when it is switched off, this is an example of resistance, which provides light and heat.
They need more oxygen to function, so gas exchange needs to increase
Power = work/time
= 500/10
= 50J/s or 50 watt
