Physics is a branch of natural science that examines the motion and behavior of matter in space and
time and the associated concepts of energy and force. Understanding how the cosmos acts is the core
objective of one of science’s most fundamental fields, physics. Its purview extends further to include the
nature and genesis of gravitational, electromagnetic, and nuclear force fields, in addition to the behavior
of things when subjected to certain forces.
Together, theory and experiment make sense while studying through Physics Sample Papers. An
experiment that measures a phenomenon can predict or support a hypothesis. At the same time, a
theory is considered valid if it can forecast how an investigation will turn out. By enabling the
measurement of phenomena in a controlled setting, the equipment list does precisely that.
Some of the Physics Laboratory Equipments are the following:
- Resistor: An electrical component known as a resistor offers electrical resistance in a circuit. It is used
to divide voltages, bias active elements, reduce current flow, and modify signal levels. - Rheostat: A variable resistor called a rheostat regulates current. By using a wiper (sliding contact)the
device, a circuit’s resistance can be changed. - Galvanometer: The galvanometer is the tool used to measure or detect very tiny currents and
voltages. The galvanometer is mostly utilized in bridges and potentiometers to display zero current or
null deflection. It functions as an actuator by creating a rotating deflection (of a “pointer”) in reaction to
an electric current running through a coil in a continuous magnetic field. - Ammeter: An ammeter is a device used to gauge the electric current flowing through a circuit,
whether a direct or alternating current. Amperes (A) are units used to measure electric currents. Digital
ammeters employ an analog-to-digital converter to display current as a numerical value instead of
analog ammeters, which move a pointer across a scale in proportion to the circuit’s current. - Voltmeter: The electrical potential difference between two locations in an electric circuit is measured
using a voltmeter. While digital voltmeters utilize an analog-to-digital converter to display voltage
numerically, analog voltmeters move a pointer across a scale in proportion to the circuit’s voltage. - Multimeter: A multimeter is an electronic measuring device containing many measurement
operations. Voltage, current, and resistance can all be measured using it. While the digital multimeter
shows readings on a screen, the analog multimeter employs a moving pointer to display them. - Battery eliminator: It is a device that receives power from a source other than a battery and
transforms that source into a usable DC voltage for a battery-powered second device. - Daniel Cell: An example of an electrochemical cell is the Daniel cell. It comprises a copper pot with
cupric sulfate solution inside a zinc electrode and an unglazed earthenware container with sulfuric acid. - Leclanché cell: It is a battery that has an anode (negative terminal) of zinc (reductant), a cathode
(positive terminal) of carbon, a depolarizer of manganese dioxide (oxidizer), and a conducting solution
(electrolyte) of ammonium chloride. - Meter bridge: A meter bridge can determine a coil’s or any other material’s unknown resistance. The
Wheatstone Bridge’s operating theory applies to this bridge. A circuit’s unknown resistance can be
measured using the Wheatstone Bridge. It consists of a galvanometer, four resistors—two of which are
known resistors, one of which is variable, and one of which is unknown. As the variable resistance, the
meter bridge is used. - Prism: A prism is a transparent optical component that refracts light and has flat, polished surfaces.
Angles between at least two of the flat surfaces are required. The traditional geometric shape is a
triangular prism with a triangular base and rectangular sides. Any substance that is transparent to the
wavelengths for which they are intended can be used to create prisms. It can be used to separate light
into its component spectral hues, or the rainbow’s colors, each of which has a unique wavelength. - Lens: An optical device known as a lens employs refraction to focus or disperse a light beam. In
contrast to a prism, which just refracts light without focusing it, a lens can focus light to create an image.
Glass or plastic are used to make lenses, which are then polished or molded into the required shape. - Thermometer: A thermometer is a tool used to measure a body’s temperature or change in
temperature. It comprises a temperature sensor—the mercury-in-glass thermometer’s bulb, which
enlarges when the temperature changes—and a visible scale that transforms the change in temperature
into a numerical value. - Tuning fork: A tuning fork’s tines (prongs) are constructed from a U-shaped bar of elastic metal.
These tines reverberate at a certain, continuous pitch when struck against a surface. The two prongs’
length and mass determine the angle a specific tuning fork produces. The air molecules nearby are
disturbed by the tines’ back-and-forth motion.
