It consists of a copper pot filled with cuprous sulfate solution, in which was immersed an unglazed earthenware container filled with sulfuric acid and a zinc electrode. The Daniel cell is a type of electrochemical cell. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat.Ī battery eliminator is a device powered by an electrical source other than a battery, which then converts the source to a suitable DC voltage that may be used by a second device designed to be powered by batteries. It works as an actuator, by producing a rotary deflection (of a "pointer"), in response to electric current flowing through a coil in a constant magnetic field.Ī potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. The galvanometer is mainly used in the bridges and potentiometer where they indicate the null deflection or zero current. The galvanometer is the device used for detecting the presence of small current and voltage or for measuring their magnitude. 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. Electric currents are measured in amperes (A), hence the name. 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.Īn ammeter is an instrument used to measure the current, either direct or alternating electric current, in a circuit. Analog multimeter uses moving pointer to display readings while digital version displays it on a screen.Ī voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit. It can measure voltage, current, and resistance. You can read more about it here.Ī multimeter is an electronic measuring instrument that combines several measurement functions in one unit. It can vary the resistance in a circuit by wiper (sliding contact) mechanism. It is used to reduce current flow, adjust signal levels, to divide voltages, bias active elements etc.Ī rheostat is a variable resistor which is used to control current. Here is the detail guide about Lab Equipment Package designed for 40 students as per school board curriculum and get school affiliation easily (CBSE/ICSE/Others).įollowing are must-have list of physics laboratory equipment:Ī resistor is an electrical component that provides electrical resistance in a circuit. And these list of equipment do just that by providing the measurement of phenomena in a controlled environment. While a theory that predicts the outcome of an experiment is considered valid. An experiment that results in measurement of a phenomena can predict or confirm a theory. Its scope further trickles down to not only the behavior of objects under the action of given forces but also the nature and origin of gravitational, electromagnetic, and nuclear force fields. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves. Physics is the natural science that studies matter, its motion and behavior through space and time and that studies the related entities of energy and force. But before that let’s understand “ What is Physics?”

In this blog, you will find a picture and an explanation for how to use each of these equipment. In most Physics labs, you'll encounter some basic common apparatus.
