 The right hand thumb rule, also known as the right-hand grip rule, is a mnemonic and visualization technique used to determine the direction of a magnetic field around a current-carrying conductor. The Right Hand Thumb Rule: Here's how the right-hand thumb rule is applied: 1. Imagine you are holding a current-carrying conductor in your right hand. 2. Align your thumb with the direction of the current flow, i.e., the conventional current flow from positive to negative. 3. Curl your fingers around the conductor. The direction in which your fingers curl represents the direction of the magnetic field lines around the conductor. To summarize: - Thumb: Represents the direction of current flow. - Fingers: Represent the direction of the magnetic field lines. The right-hand thumb rule applies to straight conductors as well as coils or loops of wire. For a straight conductor, the magnetic field lines form concentric circles around the wire. For a coil or loop, the magnetic field lines insid...

The rule of ohms:                                     Found in three dimensions in any circuit Electric current Lightning v Electrical resistance                         Among the above dimensions, a specific relationship was identified by Ohm, which is called the rule of ohms, which is as follows. The rule of ohms:                                 According to Ohm's law, the flow of fluid in any closed circuit in constant heat is in proportional to the pressure of the pressure and in the perimeter of the blockage.                      So from this rule of us                                      ...
