Which of the following calculates power dissipated by a series linear voltage regulator?
Input voltage multiplied by input current
Input voltage divided by output current
Voltage difference from input to output multiplied by output current✓Richtige Antwort
Output voltage multiplied by output current
Erklärung
All of the load current passes through the series element, and that element drops the difference between input and output voltage. Multiplying the two gives the dissipation, which appears as heat in the regulator.
