In a safety circuit, what do you look for to tell if it is a single channel or dual channel?
Homework Answers
Single channel relays are capable of accepting a single normally closed (NC) input and are unable to detect short circuit or monitored input failure in a safety circuit.
Dual channel devices can accept two inputs and have two independent circuits per input. Dual channel relays continually operate even in the event of a single circuit failure, and can detect wiring faults and input failure.

1. You lowered a patch-clamp onto a single ion channel. How would you identify what ion species it conducts? 2. You lowered a patch-clamp onto a single ion channel, which was created from RNA that you modified from RNA for a voltage-gated sodium channel gene. Name at least one feature of that ion channel you could identify that might tell you something useful about what the piece of ion channel you modified, might do.

You are upgrading the memory of a dual-channel architecture computer that currently has two sticks of SDRAM DDR3 by adding an identical third stick. As you are about to close the computer case, your supervisor comes by and tells you that your upgrade won’t be successful. What does he tell you is the problem? A. The computer you are working on uses dual-channel memory and memory upgrades must always be installed in pairs. B. When you upgrade a computer’s memory,...
