Question

How should a junction diode connected to a battery to keep it backwards?
​

Answer 1

Answer:

Below...

Explanation:

If the positive side of a voltage source is connected to the positive end of the diode and the negative side is connected to the negative end of the diode the diode will conduct current. If the diode is reversed, the current is blocked

Answer 2

Backward biased junction:

Explanation:

• The process by that, a p-n junction diode blocks the electric current in the presence of applied voltage is termed reverse-biased p-n junction diode.
• In reverse biased p-n junction diode, the positive terminal of the battery is connected to the n-type semiconductor device and the negative terminal of the battery is connected to the p-type semiconductor device.
• When the external voltage is applied to the p-n junction diode in such a way that, the negative terminal is connected to the p-type semiconductor material and the positive terminal is connected to the n-type semiconductor.
• The holes from the p-side are attracted to the negative terminal whereas free electrons from the n-side are attracted to the positive terminal.
