Electrical Conductance and Insulation OVERVIEW: Every thing in the world is differentiable on the basis of its electrical conductance. Some things are called insulators and these substances never conduct electricity. they include things such as cold air‚wood and plastic. Then there are things that conduct electricity and current flows through them‚ they are called conductors. examples of conductors are most metals like copper and steel. Other materials that are sometimes used as conductors are

technology on my headset will rely on bone conduction (bone conduction is something where technology goes through their skull and to their brain) so that whatever they want listen to‚ they do not have to wear any headphones. I chose bone conduction because for some people who cannot hear anything I can help them by helping them listen again(Alec). Just incase people do not want others to see that they have that technology on their head they can put that bone conduction into a hat so it can match their style

low temperature. The bigger the temperature difference‚ the faster the heat transfer. Heat moves by three different processes: Conduction - mainly in solids Convection - mainly in liquids and gases Radiation - any state of matter can absorb/emit infrared radiation. Conduction Vibrations in matter are passed on to transfer heat energy. This is called conduction. Insulator - a material that stops energy being transferred. Solids are good conductors because the particles are closer together

Abstract: The purpose of this experiment was to examine how the compound action potentials propagate down the sciatic nerve of a frog based on varying stimuli. Before the nerve could be tested it needed to be extracted from the thigh of the frog and then submerged in saline. Several varying stimuli were used and recorded by a software package. The second experiment requires a constant stimulus with varying reference pin locations. From this the velocity of the action potential propagated can be

BIOSC 048: Problem Set Questions 1. Given that cell A has significantly more nongated K+ channels than cell B‚ which cell has the larger resting membrane potential? Explain. If the permeability to K is higher in A than in B‚ then the resting membrane potential (rmp) will be closer to the equilibrium potential in cell A‚ which means the rmp will be more negative in cell A than in cell B; or in other words‚ the potential difference will be LARGER in cell A. 2. Predict the effect of a reduced
