- analog swithcing
A: reed

Q: A limitation of EMR is ____________.
- no OFF-state leakage current through open contacts
- they normally have a multipole, multithrow contact arrangement
- they generate EMI on power lines
- their contacts can switch AC or DC
A: no OFF-state leakage current through open contacts

Q: A(n) _________ relay is an SSR that allows the load to be turned ON at any point on the AC sine wave.
