Hi!How can I calculate the thin film resistor's power dissipation.For example, for a FET bias using, 0.5V voltage will drop on the resistor and near 100mA current cross it .
Best regards!

The power disipated in a resistor is basically the voltage across the resistor multipled by the current through it.
P = IV = 0.5V * 0.1A(100mA) = 0.05Watts (or 50mW)

When you bought the resistor, what did the shipping package list as its power rating?
