WebDec 2, 2024 · For a 500 Ohm load resistor, the power dissipated at 20 mA is 0.2 Watts. A good choice for the resistor’s power rating is at least 2 Watts because such a load will not heat up very much. Even at full loop current there won’t be a voltage change across the load resistor due to heat from power dissipation instead of actual loop current changes. WebThe unit of power is the Watt (W) Power is additive in any configuration of a resistive circuit—series, parallel, or series-parallel; P total = P 1 + P 2 + . . . P n . Related Content. …
