Answer: A
Share your understanding of this question with the correct explanation.
The Cork Screw rule is used to find the direction of the current. Therefore, the correct answer is A: “direction of current.”
Here’s a further explanation:
The Cork Screw rule, also known as the Right-hand rule or the Right-hand grip rule, is a mnemonic or visualization technique used to determine the direction of a current in a conductor or the direction of a magnetic field around a current-carrying conductor.
To apply the Cork Screw rule, you can use your right hand with the thumb pointing in the direction of the current. The curled fingers represent the direction of the magnetic field or the circular path of the magnetic field lines around the conductor.
By convention, the direction of the current is defined as the direction of the flow of positive charges. However, in reality, electrons (which are negatively charged) actually flow in the opposite direction. So, when using the Cork Screw rule, you imagine the flow of positive charges in the direction of the current.
To summarize, the Cork Screw rule is used to find the direction of the current in a conductor. It can help you determine the orientation of the magnetic field around a current-carrying conductor.
