Types of Physics Lab Apparatus and Their Uses
There are many types of physics lab apparatus that are used for different purposes. Here are some of the most common ones:
Electrical Equipment
These are devices that are used to create, control, measure, or detect electric currents or voltages. Some examples are:
Resistor: A resistor is an electrical component that provides electrical resistance in a circuit. It is used to reduce current flow, adjust signal levels, to divide voltages, bias active elements etc.
Rheostat: A rheostat is a variable resistor which is used to control current. It can vary the resistance in a circuit by wiper (sliding contact) mechanism.
Multimeter: A multimeter is an electronic measuring instrument that combines several measurement functions in one unit. It can measure voltage, current, and resistance. Analog multimeter uses moving pointer to display readings while digital version displays it on a screen.
Voltmeter: A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage of the circuit while digital voltmeters give a numerical display of voltage by use of an analog to digital converter.
Ammeter: An ammeter is an instrument used to measure the current, either direct or alternating electric current, in a circuit. Electric currents are measured in amperes (A), hence the name. Analog ammeters move a pointer across a scale in proportion to the current of the circuit while digital ammeters give a numerical display of current by use of an analog to digital converter.
Galvanometer: The galvanometer is the device used for detecting the presence of small current and voltage or for measuring their magnitude. The galvanometer is mainly used in the bridges and potentiometer where they indicate the null deflection or zero current.
Mechanical Equipment
These are devices that are used to apply force, measure force, or demonstrate mechanical phenomena. Some examples are:
Vernier Caliper: A vernier caliper is an instrument used for measuring length or diameter with high precision. It consists of two scales: a main scale and a vernier scale that slides along the main scale. The vernier scale has a smaller unit than the main scale and allows reading fractions of a unit.
Screw Gauge: A screw gauge is another instrument used for measuring length or diameter with high precision. It consists of a U-shaped frame with a spindle that moves through a nut when rotated by a thimble. The spindle has a circular scale on it that indicates fractions of a rotation. The frame has a linear scale on it that indicates whole rotations.
Balanced Beam: A balanced beam is a device used for measuring mass by comparing it with known masses. It consists of a horizontal beam supported at its center by a fulcrum. The beam has two pans hanging from its ends where masses can be placed. The beam c481cea774
