What is called Thermal Expansion? Upon heating, all matters which are either solid, liquid or gas expand in length, area or volume. This is called thermal expansion. All matters are composed of atoms and molecules.Read More →
What is a Thermometer? A thermometer is defined as a device which is used to measure the temperature of a body. Temperature is basically a measure of the amount of kinetic energy of the particlesRead More →
What is Biot-savart Law? If an electric current is passes through a conductor, it start to behave like a magnet. This means that, the current carrying conductor get magnetized due to current flowing through it.Read More →
What happens when a charge moves in Electric Field? When a charge is projected to move in an electric field, it will experiences a force on it. The projected charge while moving through the regionRead More →
What is magnetic effect of current? If an electric current is passes through a conductor, it start to behave like a magnet. This means that, the current carrying conductor get magnetized due to current flowingRead More →
What is called Magnetization? When a magnetic material is placed in the region of a magnetic field produced by another magnet, it acquires magnetic properties by induction. This phenomenon is called magnetization. The extent ofRead More →
What is Earth’s Magnetic Field? Our earth behaves as a magnet and its magnetic field is called earth’s magnetic field. Magnetic field of the earth changes from place to place and time to time onRead More →
What is Magnetic Field Intensity? The force of attraction or repulsion experienced by an unit north pole strength placed in the magnetic field of a magnet is called the magnetic field intensity. Magnetic Field MagneticRead More →
What is a Potentiometer? A potentiometer is a device which is used to measure the EMF of a cell without drawing any current from it. Hence, a potentiometer gives very accurate results because the effect ofRead More →
What is called a Magnetic Force? The force of attraction or repulsion exerted by a pole of magnet on another magnet or a magnetic material is called magnetic force. The magnitude of magnetic force isRead More →
What is Kirchoff’s Law for electrical circuit? Kirchoff’s law is very helpful in solving complicated electrical circuits consisting of a combination of cells and resistors. The law is consisting of two statements – Current lawRead More →
What is Electromotive Force? Electromotive force of a source of electric current supply is defined as the potential difference between the terminals of the cell in open circuit i.e. when no current is drawn from theRead More →
What is Lami’s Theorem? In analyzing of the force problems, sometimes we require to evaluate the effect of a force in a certain direction of our interest. This is done by resolving the forces inRead More →
What is an Electric Circuit? An electric circuit is a closed loop or path consisting of a network of electrical conductors, resistors, electronic components and other electrical elements where electrons can flow through it uninterruptedly.Read More →
What is called Resolution of Forces? In analyzing the force problems, sometimes we require to evaluate the effect of a force in a certain direction of our interest. This is done by resolution of forcesRead More →
