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 Perio...
