Make a circuit model of a cell.

a. Explain at the molecular level which part of a neuron corresponds to which of the components of an electrical circuit: resistors, potentiometer (variable resistor) and capacitors.

b. What is the voltage source in this circuit?

c. Draw a circuit model of a cell by drawing a very simplified cell (cell body) and draw into this drawing the components of the electrical circuit (battery, resistor, potentiometer, capacitor) using their standard symbols.
