Which one is correct in MPPT mode of a solar cell? Voc > Vmp and Imp > Isc Voc < Vmp and Imp < Isc Voc > Vmp and Imp < Isc Voc < Vmp and Imp > Isc

The correct answer is: Voc > Vmp and Imp < Isc

Here's why:

1. Voc (Open Circuit Voltage) is the maximum voltage available from a solar cell, and this occurs at zero current. On the other hand, Vmp (Voltage at Maximum Power Point) is the voltage at which maximum power is available from a solar cell. Since no current flows when the voltage is at Voc, the power (which is the product of voltage and current) is zero. Therefore, Voc is greater than Vmp.

2. Imp (Current at Maximum Power Point) is the current at which maximum power is available from a solar cell. Isc (Short Circuit Current) is the maximum current available from a solar cell, and this occurs at zero voltage. Since no voltage is present when the current is at Isc, the power (which is the product of voltage and current) is zero. Therefore, Imp is less than Isc.
