The heating effect of electric current is a phenomenon that occurs when an electric current passes through a conductor and results in the generation of heat. This effect is commonly observed in everyday life, such as when an electric stove is used to cook food or when a light bulb is turned on and produces light and heat.

In a laboratory setting, the heating effect of electric current can be studied through a series of experiments. One such experiment involves passing an electric current through a conductor and measuring the temperature change that occurs. This can be done using a thermocouple or a thermometer to measure the temperature of the conductor before and after the electric current is passed through it.

To begin the experiment, the conductor is first connected to a power supply, such as a battery or a voltage source. The power supply is then turned on and the electric current is allowed to flow through the conductor. As the electric current passes through the conductor, it causes the particles within the conductor to vibrate, which generates heat.

The temperature of the conductor can then be measured using a thermocouple or a thermometer. The temperature readings should be taken at regular intervals, such as every minute or every five minutes, to ensure that an accurate measurement of the temperature change is recorded.

Once the experiment is complete, the data collected can be analyzed to determine the relationship between the electric current and the temperature of the conductor. This can be done by plotting the temperature readings on a graph and examining the slope of the graph. A steep slope indicates that the temperature of the conductor is increasing rapidly as the electric current increases, while a shallow slope indicates that the temperature is increasing more slowly.

Overall, the heating effect of electric current is a useful and important concept to understand, as it has a wide range of applications in everyday life, such as in the operation of electric appliances and the generation of electricity. By studying the heating effect of electric current in a laboratory setting, students can gain a deeper understanding of this phenomenon and how it works.

## Lab Report 5 Electricity is often converted into other sorts of energy like heat, light energy, etc. Then, learned when conservation of energy the electrical energy being converted to thermal energy. Effects of Electric Current When a current flows through a conductor, there are a number of signs which tell if a current is flowing or not. Electric cable heating system using internal heat source: This type of electric cable heating system uses an internal heat source, such as a boiler, to heat the air in the pipe. If the time for which the current is passing through the conductor is doubled, then the heat produced is doubled. From the time we wake up till the time we sleep at night, our life is dependent on electricity. Hence, the source has to supply energy equal to V × I in time t.

## Lab 7 The work done to overcome this resistance to current generates heat in that conductor. The atoms and molecules in the substance are therefore responsible for conduction. For my experiment, I have chosen to vary the current while keeping the all the other factors constant. The current given was 2 A and its resistance is 3 ohms. Whenever the electrical current flows in the coil, it quickly becomes warm or heated, which is then widely used to heat our cooking vessels. Turn on the power supply to 2 amperes 6. Hence filament of bulb emits light and heat.

## PHYS 1442 Theory: When there is an electric current in a resistor, an electric charge q moves because of the potential difference, and electrical energy is continuously being transformed into thermal energy within the resistor. If you get stuck do let us know in the comments section below and we will get back to you at the earliest. The advantage of this type of electric cable heating system is that it is self-sufficient and doesn't require any outside energy sources. Well, this iron is the most basic example of heating effects of electric current in our everyday life. In mountain areas, electrical room heaters are used to keep their rooms warm and heated to save themselves from the exhaustive cold outside. Part A: Photo Electric Effect The photoelectric effect for the backing voltage was recorded as 0Volts whereas the tube current observed to be o.

## Heating Effect of Electric Current: Concept, Joule's Law, Uses Henceforth, the present flowing within the external circuit is directed far away from the positive terminal and toward the negative terminal of the battery. Why do we only use an iron? Energy is conserved in the experiment, but the major sources of error in the experiment can be the human error for instance I put the 2 amperes, but I got different number of resistances. Use temperature sensor to test the temperature of water 5. In the heating effect, the electrical energy is converted into heat energy. By evaporation or natural conditions by subject of lab and make any level is being propelled from soils by breeding cycle from the overheating in contact with short out. The loss of energy is compensated by the source to maintain a uniform current in the wire.

## Heating Effect of Electric Current The force that acts on the electrons to make them move in a certain direction is known as electromotive force and its quantity is known as voltage and is measured in volts. To maintain the flow of current the source needs to expand some energy. Evaporation is the process where particles from a liquid form a vapour when the temperature of the liquid is below its boiling point. This appears to be a loss of energy. The electrical heating effect of the electrical current is most commonly and widely applied and used in our daily life.

## Electric Current and its Effects When an electric current passes through a conducting wire, the wire becomes hot because of the generation of heat in the wire. A device or an appliance that works on a higher current needs a greater value of fuse and vice versa. The heating action of current is what causes the Heating effect of Current. The amount of water flow is proportional to the pressure placed on the top. Hence, the idea of the heating effect of electric current and its applications will be covered in this article in detail! Let us learn more about the heating effect of electric current. IEC Photoelectric Unit Results Data Analysis: There are three parts carried out in this experiment.
