Power Dissipation and Energy Absorption
What is Power dissipation in a circuit? Any resistor in a circuit that has a voltage drop across it dissipates electrical power . This electrical power is converted into heat energy hence all resistors have a power rating. This is the maximum power that can be dissipated from the resistor without it burning out. How to calculate power dissipation First, we use Ohm's law ( V = I × R ), to find the current through the resistor. The voltage across the resistor is V = 9 V. The resistance of the resistor is R = 100 Ω. Then, we can use the power rule ( P = I × V ), to find the power dissipated by the resistor. What is Power energy absorption? Occurring with absorption of energ y or heat- absorbing . Antonyms: energy -releasing
