Hi
in a circuit that consists of a 9V volt power source and a 100ohm/5W resistor (these little bricks) if i'm correct the current that passes through the resistor should be 90mA and the power dissipation on the resistor should be 810mW.
in practice i can see that the resistor gets hot..and i'm wondering why since it should
withstand 5W...
