Question

how should a junction diode be connected to the battery to keep it facing forward​

Answer 1

Forward Bias in P-N Junction Diode:

• In an ideal P-N junction, the resistance showed by the diode in forward bias is zero (practically very less).

• In order to connect a junction diode in forward bias, the p type semi-conductor side has to be connected to the positive terminal of cell/battery.

• Similarly, the n type semi-conductor side has to be connected to the negative terminal of the cell/battery.

• In forward bias, the depletion layer becomes very small, and the current flows in order of milli-amperes.
