Here, if theelectric potentialof both battery cells is exactly the same, there is no circulatingcurrentin the circuit and hence the galvanometer shows null deflection. Theworking principle of potentiometerdepends upon this phenomenon. Now let’s think about another circuit, where abatteryis connected...
Potentiometer also known as pot is generally used in circuits to provide variable resistance or variable voltage. The heart of the potentiometer is a resistive strip inside it through which one can adjust the amount of resistance/voltage to pass in a circuit through it. Potentiometers are commonly...
Name the principle on which a rocket works. What is the principle of potentiometer? What is the principle involved in the Sonometer experiment? Explain superconductivity under high pressure in relation to bond distance. State the principle of reversibility of light with the help of an example. ...
View Solution In a potentiometer experiment, the balancing length with a resistance of 2Ω is found to be 100cm, while that of an unknown resistance is 500cm. Calculate the value of the unknown resistance. View Solution Recommended Questions Answer the following: (a) Write the principle of w...
Construction of Potentiometer The basic working principle of this is based on the fact that the fall of the potential across any portion of the wire is directly proportional to the length of the wire, provided wire has a uniform cross-sectional area and the constant current flowing through it....
Now that the working principle is quite clear, let’s see, the construction and types of rheostats. Construction of Rheostat: The construction of rheostat is same as that of a potentiometer, as discussed in detail in our article about potentiometers. Similar to the potentiometer, a rheostat has...
Thermocouple Working Principle Thethermocouple principlemainly depends on the three effects namely Seebeck, Peltier, and Thompson. See beck-effect This type of effect occurs among two dissimilar metals. When the heat offers to any one of the metal wires, then the flow of electrons supplies from ho...
The circuitry is also granted with provisions to regulate sensitivity and time delays with the help of potentiometer adjustments. In general, anRF Admittance level transmitterworks in an identical fashion as aCapacitance transmitter. However, there are two major modifications in the design which includ...
The work coordinate system computing section computes the coordinate axes of the work coordinate system in accordance with the above-described principle. Namely, the force detected by the force sensor 3 is converted by the force computing section 9 and the coordinate conversion section 10 into the ...
