Heating Effect of Electric Current Formula
Let us assume a current I that is flowing through a resistor that has a resistance of R as shown in the circuit. Let the potential difference across ends of the terminals of the battery be V. Let us assume to be the time during which a charge of Q amount flows across the circuit. The work which is done in moving that charge Q through a potential difference V is V × I.
Hence, the source has to supply energy equal to V × I in time t. Therefore, the power input to the electrical circuit by the source is
P = V × Q/t
= V × I
Or the energy that is being supplied to the circuit by the source in time t is P × t, that is, V × I × t. This extra energy generated gets dissipated in the resistor in the form of heat. Therefore, for a steady and fixed current I, the amount of heat denoted by H that is produced in time t is
H = V × I × t
Heating Effect of Electric Current
Heating Effect of Electric Current is a phenomenon that is generally used in our daily life. The electric kettle, toaster, heater, and other appliances are utilized as alternates for traditional cooking and laundry methods. Electric bulbs, which are an alternative to conventional lighting, utilize the same concept. Over time, these technologies have revolutionized the world. Conductors or Wires produce heat energy when a current pass through them. This is because of the fact that when an electric current passes through it, fast electron collisions start to occur. This concept or phenomenon is known as the Heating Effect of Electric Current. Hence, the idea of the heating effect of electric current and its applications will be covered in this article in detail!
