Question

What is open curcuit?​

Answer 1

Answer:

Open-circuit voltage is the difference of electrical potential between two terminals of a device when disconnected from any circuit. There is no external load connected. No external electric current flows between the terminals

hope it helps you ♥✌️

Answer 2

ʜɪ ᴍᴀᴛᴇ:-

ᴛᴏ ᴜɴᴅᴇʀsᴛᴀɴᴅ:

Open circuit is given to a circuit that current will not be able to flow through it.

So open circuit is any circuit that not pass current when potential difference is established across it, hence its resistance is infinity.

My definition:

A circuit that will not pass current when potential difference exist.
