Document Summary
Voltage: electrical potential difference aka electrical potential energy. Resistance: the difficulty of current moving through elements of a circuit. Capacitance: the ability of a circuit element to separate charge. Solve for i from ohm"s law --> i=v/r. Add up i as the reciprocal of 1/r. Capacitance: ability for charges to interact / resist charges / separate charges of opposite sign. Greater density of charges on capacitor plates --> greater force acting on charge --> greater potential difference across capacitor c. Capacitance of parallel plate is determined by its area and distance between the two plates i. Increasing distance --> decreasing capacitance d. e. f. g. Lipid bilayer acts as a capacitor since we should see them as a series of parallel capacitors with ion channels that act as. 1/c = 1/c1 + 1/c2 + 1 / c3. Current was controlled by us which is why there are specific / perfect squared peaks.
