How can you define power dissipation in a resistor?

In: Science, Electrical Engineering [Edit categories]

Answer:

Power dissipation of a resistor or any load is the amount of power (in watts) that is converted to heat, light, or other form of energy.

In a resistor, power dissipation is defined by Ohm's law

P = I^2 * R

Power dissipated equals current through the resistor squared times the resistance in ohms.

Since the power is converted to heat, a resistor has a maximum dissipation rating set by the manufacturer, above which the resistor will be damaged.

How can you define power dissipation in a resistor in series or parallel circuit?
Power dissipation in a resistor, or any other type of load, for that matter, is measured in watts and calculated as volts times amperes. It does not matter if the resistor is in a series or a...
How can you define power dissipation in transistors?
Power dissipation is measured in watts. Watts is Amps times Volts. Measure the voltage across the transistor, measure the current flow through it, and you can calculate watts very easily. (Of course,...
