Typically voltage-current characteristics are shown in the figure at two different solar radiation levels, for each of which Voc = open-circuit voltage, Isc = short-circuit current. The ideal power of the cell is Vo.Isc. The maximum useful power is the area of the largest rectangle that can be formed under the I-V curve.

The amplifier over temperature sensor will trigger at 195 °F (90 °C). Make sure the cooling fan for the servo amplifiers operates correctly. If the fan does not operate correctly, measure the voltage it receives. Disconnect the cable from the cooling fan. Measure the voltage between the leads of the cable.

This type of motor can be adapted for use as a servo motor, described elsewhere in this chapter. Single-phase induction motor with embedded stator coils . Single-phase induction motors may have coils embedded into the stator for larger size motors. Though, the smaller sizes use less complex to build concentrated windings with salient poles.

In Open Circuit, the electric current(charged particles) does not flow from an active energy source to the connected load or other components due to the incomplete path. If any components disconnect or break from the circuit, this circuit works as the open circuit. Sometimes, the open circuit shows like OFF condition or fault condition.

Ground-Reservoir Analogy. The function of a ground wire in an electric circuit is in many ways analogous to the reservoir attached to the water circuit. Once the pipe is filled with water, the pump can circulate the water without further use of the reservoir, and if it were removed it would have no apparent effect on the water flow in the circuit.
