When discussing a power supply the_______ resistance is equal to the output voltage divided by the total current drawn, including the current drawn by the bleeder resistor:
- Aideal
- Brectifier
- Cdifferential
- Dload
Correct answer: D — load. From the official ISED question bank, verified word for word.
Why
The load resistance represents the total opposition to current flow in the entire circuit connected to the power supply, which includes both your equipment and the bleeder resistor. The full explanation — and one for every question — is in Pro.
