The graph of a spring or helical spring is a representation of the extension with the load. The graph is a must to indicate the fact that the extension of a spring is completely dependent on the load that is applied. This graph is also referred to as the Extension-load graph. A few things that are going to be observed through this experiment, firstly a perfect lab set up is needed, and then comes the experiment data set and the process where those extension load graph is going to be interpreted. Aim The experiment aims ... Read More

The tutorial mainly gives focuses on finding a convex mirror’s focal length and for this experiment; a convex lens is used. In this experiment, some materials are needed and they are essential for this examination. Here a bench is the most essential material and two needles are required here. It is seen that if the concave lens was not there and the object was at a distance then the focal length of the convex lens will create a real image. Aim The main aim of this experiment is to find the focal length of a concave lens with the ... Read More

The inclination of a certain material proportionally depends on the downward force that is influenced by the gravitational pull of the earth. In this scenario, finding the relationship between these two aspects can depend on a plotting graph in order to outline the relationship with a logical explanation. A particular graph needs to be plotted in order to study the relationship between the angle of inclination (θ) and the downward force denoted by sin θ. Required materials The process of finding the relationship involves a series of steps and materials that can help in the succession of the procedure ... Read More

Forward bias and reverse bias is always present within a standard diode, especially while drawing the characteristics of I-V junction and P-N junction. The curve of these junctions is dependent on the forward and reverse bias and follows a series of steps and procedures to successfully draw the curve within a standard diode. Definition of Forward and Reverse Bias Forward bias is the state where the external voltage is always delivered across the P-N junction within a standard diode. In the set-up process of the forward bias, the P side of the standard diode is always attached to the ... Read More

The Young's modulus is commonly used when the lengthwise compression or tension changes within a material. It is a numerical constant that helps in describing the elastic properties and undergoing tension or compression in real-time. The determination of the elasticity of a material becomes easier with the help of Young’s modulus as it is capable of measuring the compression or tension within a certain electrical system. What is Young’s modulus? Young’s modulus is a property of a material that influences the deformation and elasticity of material in real-time. It can also be defined as the ratio of tensile stress ...

Potentiometer is usually defined as a three-terminal resistor. This instrument has been generally applied for measuring the production of an adjustable voltage divider while rolling or sliding contact. The primary application of the Potentiometer is for the determination of the internal resistance of primary cells. In accordance with the theory of Thévenin, the power source can be acknowledged as a voltage source that can be ideal in series with impedance, usually termed as internal resistance. Aim The main of this experiment is to determine the internal resistance of a given primary cell with the help of a potentiometer. ... Read More

The measurement of the fluid or gas is defined as the viscosity of the respective gas or liquid. This specific concept helps to determine the fiction along with the movement of liquid. Experiments have stated that liquid that has a low viscosity can flow easily because while being in motion, the molecules of the liquid develop fiction. Based on these concepts, the tutorial will explain an experiment that helps to determine the coefficient viscosity of the liquid by measuring the terminal velocity of a given spherical object. Aim The main of this experiment is to determine the ... Read More
