what do you understand by heating effect of current?

Joule heating, also known asohmic heatingandresistive heating, is the process by which the passage of anelectric currentthrough aconductorreleasesheat. The amount of heat released is proportional to the square of the current such that
This relationship is known asJoule's first law. TheSI unitofenergywas subsequently named thejouleand given the symbolJ. The commonly known unit of power, thewatt, is equivalent to one joule per second. Joule heating is independent of the direction of current, unlike heating due to thePeltier effect.

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
