Benefits between using a Relay or Transistor? Answered
I am unclear as to the potential benefits of using a relay versus a transistor and vice versa. Does some one have a good link or explanation? In the project that I am working on I need to be able to turn power on/off for a device that uses 500mA at 7.5V. Is there one that I should use? Everything is DC not AC if that makes a difference. Thanks in advance for your help.
