Unformatted text preview: 2.7 Evidence that the resting potential is determined by K + concentration gradient. For sodium: E Na = (58/+1) log (450/50) = 58 log (9) = +55 mV For chloride: E Cl = (58/1) log (560/40) =58 log (14) = 67 mV A current flows in response to closing the switch. Current is constant. Current measured in units called amperes (1coulomb/sec). The relationship of current and voltage is dictated by Ohm’s law, V=IR Resistance is measured in units called ohms In Neurobiology we often use the inverse of resistance, called conductance, i.e. V=I/g; units here are siemens. V R = IR V C = V B (1etau/RC )...
