When a conductor is carrying the current and it is placed in the magnetic field then a magnetic force is experienced by the conductor. The direction of this acting force is always right angles to the plane that is containing both the magnetic field and the conductor. Concerning the above diagram, F is denoting the … Read more

Electric current by name it is clear that it is the rate of flow of electric charge past a region and an electric current is said to exist where there is a flow of net or electric charge through a region. Ampere is the SI unit of electric current and it is measured by using … Read more

The cyclotron is one of the earliest kinds of particle accelerators, but it is still used at the initial stage of some large and multi-stage particle accelerators. It uses the magnetic force on the moving charges for bending them into the semi-circular pathways between the accelerations due to the applied electric force. By the applied … Read more

A resistor is a passive of two-terminal electrical components that implements electrical resistance as a circuit element and this electronic circuits carbon resistors which are used to reduce the current flow, divide voltages, adjust the signal level and terminate transmission lines. Some of the fixed resistors have a resistance that only changes with a slight … Read more

Biot – Savart law and its Application to Current Carrying Circular Loop Biot-Savart’s law is the equation used for representing the magnetic field, produced due to a segment that is carrying the current. The segment that is carrying current is taken as the vector quantity. A magnetic field is produced by the current-carrying circular conductor … Read more

Ampere’s Law and its Applications to Infinitely Long Straight Wire Ampere’s law states that the magnetic field in the space around the electric current is proportional to an electric current that is serving as its source, just like the electric field in the space is proportional to the charge that is serving as its source. … Read more

The magnetic field describes the influence of electrical charges in magnetized material and relevant motion. A magnetic field can only be generated when the electrons move through the electrical conductor. The geometric shapes of flux are produced by moving electric current through the shapes which are similar in the electrostatic field. There are many ways … Read more

1. Find the equivalent capacitance of system of capacitors shown below. Equivalent capacitance of two capacitors each having capacitance C are connected in series. So,equivalent capacitance = $C/2$ Therefore, the circuit can be drawn like, $C/2$, $C$and $C/2$are now in parallel. So the equivalent capacitance, $C/2$+$C$+ $C/2=2C$ Four capacitors are connected as shown below. If … Read more

Potential due to an electric dipole: Let us consider charge $-q$ is placed at point $P$ and charge $+q$ is placed at point $Q Figure:8.a Electric potential at point $R$ due to electric dipole would be sum of potential due to both the charges $+q$ and $-q$. So, ………………….. (1) Draw two perpendiculars $PC$ and … Read more

Electrostatic potential at any point of an electric field is defined as potential energy per unit charge at that point. Electric Potential Energy: Let us consider a system of two point charges $q$ and $q^{‘}$ (positive test charge) separated by a distance $r$ Figure:7.a Charge $q$ is fixed at point $P$ and is displaced from … Read more
