Rheobase Study guides, Class notes & Summaries

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