'Flakka': How dangerous is the new street drug? A designer street drug called 'Flakka' is making headlines again with a new incident involving four people going on a rampage in Sullivan, Missouri. What is Flakka and just how dangerous is it?
Voltage clamp. The voltage clamp is an experimental method used by electrophysiologists to measure the ion currents through the membranes of excitable cells, such as neurons, while holding the membrane voltage at a set level.
A single volt is defined as the difference in electric potential across a wire when an electric current of one ampere dissipates one watt of power. It is also equal to the potential difference between two parallel, infinite planes spaced 1 meter apart that create an electric field of 1 newton per coulomb.
