Question

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

Answer 1

FORWARD BIASED JUNCTION DIODE

EXPLANATION:

To connect the junction diode as forward-biased you need to do the following:-

Connect the positive side of the battery to the anode side of the junction diode which is also known as the P-side. Later, connect the negative side of the battery to the cathode of the junction diode, also known to be the N-side. This is the condition in which the junction can be connected to the battery to keep it facing forward ( Forward Biased Junction Diode ).

In such a condition the height of the potential barrier at the junction is lowered by an amount equal to the given forward biasing voltage.

Answer 2

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.
