Wheatstone bridge or bridge circuit is a topology of the electrical circuit in which two circuit branches are bridged by the third branch which connects first two branches at some intermediate point and this was originally developed for laboratory purposes and it can find many applications of both linear or non-linear which includes instrumentation, filtering, … Read more

Torque Experienced by a Current Loop in Uniform Magnetic Field; Moving Coil Galvanometer-its Current Sensitivity and Conversion to Ammeter and Voltmeter Torque is the twisting force that causes the rotation. The axis of rotation is a specific point where there is a rotation of the object. τ = F×r Here F is used to denote … Read more

The long wire that is wound in the form of the helical coil is termed as the solenoid. Commonly, the solenoids are used in the experimental research where there is the involvement of the magnetic field. The winding of the solenoids is much easier, the magnetic field at its center is quite uniform and is … Read more

Potentiometer has gained many aspects in the field of science and especially in the field of physics as it is a three-terminal resistor with a sliding or rotating contacts that forms an adjustable voltage divider and another aspect is that it is a measuring instrument which is essentially a voltage divider used for measuring electric … Read more

Ohm’s law was the most important quantitative description of the physics of electricity and it states that current through a conductor between two points is directly proportional to the voltage across it’s two points. In physics Ohm’s law is rather used to refer various generalizations of the other law as vector form of law is … Read more

What is actually meant by internal resistance and why it should be measured was the biggest question to be solved since the example of battery came up as battery just like other component is an electric circuit which has resistance and this resistance is known as internal resistance. By this it is clear that applying … Read more

Kirchhoff established his name in the world of physics by applying two applications of physics in electric circuits. The first application states that current which is flowing into the node must be equal to the current out of the node and this is called Kirchhoff’s current law. The second application is called Kirchhoff’s voltage law … Read more

Internal resistance in simple words means the electrical resistance inside the batteries and also in the power supplies which can limit the potential difference that can be supplied to external this is caused when there is current or electric circuits are there in the device or there can be a voltage drop or source battery … Read more

The magnetic force can cause the movement of the charged particles, in the spiral or the circular paths. In outer space, the cosmic rays are the energetic charged particles, and only some of them can approach the earth. Due to the magnetic field of the earth, they can be forced into the spiral paths. By … Read more

Force between Two Parallel Current-Carrying Conductors-Definition of Ampere In the current-carrying conductor, there is always the existence of a magnetic field. This magnetic field exerts the force on the current-carrying conductor. It can be said that when the two conductors are placed near to each other then both of them will exert a magnetic force … Read more
