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)
