An off-grid installation has a 1HP pump that is on 10% of the time and a 20W light that is on 100% of the time. What is the monthly energy use? - correct answer 68KWh 1HP = 746W 746W * 0.1 * 24hours * 30days = 53712Wh 20W * 24hrs * 30days = 14400Wh 14400 + 53712 = 68112Wh 68kWh What kind of ground faults do most inverters detect? - correct answer DC Inverters detect dc ground faults. AC ground faults are detected on the AC side of the inverter at the distribution paned (MSP, load center...

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...
