Title: Quiz 8-7: Amp Load and Power Supply - 15 Minutes
Course: Basic Electrical Theory and Wiring (Sandbox) > Section: Module 8: Power

Q: Calculate the DC Power supply needed to run the following items of equipment:

- 24 VDC 12 W Solenoid - Qty = 3
- 24 VDC 4 to 20 mA loop power transmitters (Tran smites a mA signal between 4 mA up to 20 mA) - Qty = 10

Note!
This means that any one of these devices could be using 4 mA or up to 20 mA.

- 24 VDC 30 W solenoid - Qty =2

Then, select which power supply should be used based off the answer. Keep in mind that the higher the Amps supplied, the higher the cost. We want to be able to run the equipment with the lowest cost.
- 2.5 A DC Power Supply
- 3 A DC Power Supply
- 4 A DC Power Supply
- 5 A DC Power Supply
- 10 A DC Power Supply
A: 5 A DC Power Supply
