CLEP Chemistry Latest Update Graded A John Dalton Proposed that matter is composed of atoms; these atoms have different identities called elements, which combine to form compounds; measured masses of reactants and products. J.J. Thompson Observed deflection of particles in a cathode ray tube; proposed that atoms are composed of positive and negative charges; developed the plum pudding model of the atom Robert Millikan Calculated the charge-to-mass ratio of electrons using oil drops falling in ...

Rheobase - the lowest point on a strength duration curve at an infinitely long pulse duration Chronaxie time - the pulse width at twice the rheobase value. It approximates the most efficient stimulation pulse duration Charge (formula) - Charge= I(current) x T(time) Furman's formula - Energy(microjoules)= I(current)xV(voltage)xT(pulse width) Ohms law formula - Voltage(electromotive force)= I(current/flow of electrons) x R(resistance to current flow in ohms) Functional Refractory P...
