Who found heating effect of electric current?
Joule showed the heating effect due to the resistence of wire which cary the current.
State the situations where heating effect of electric current is undesirable?
negative effect of science .. with picture
Which effect of electric current is utilised in the working of an electrical fuse?
The heating effect is used. Normally the current flows through the fuse without undue heating. But if too much current passes through, the fuse will heat and melt, thus stopping the current which could cause a fire if it was not stopped .
What happens when freon is heated?
It`s pressure rises continual heating will cause it to decompose.
What happens to solids and liquids on heating?
Solids turn into liquid. Liquid boils. Simple
In a heat pump installation the direction of flow refrigerant vapor is reversed through what component when the cycle is reversed from heating to cooling?
The reversing valve
Is electirc fire cause by heating effect of an electric current?
Yes, that's basically what happens.

How can iron be demagnetized?
an iron can be demagnetised by ;-hammering it while facing east _west direction -hitting it hard on the ground -connecting it into an ac current while facing the east _west direction .
How does alternating current and direct current affect heating ventilation and airconditioning?
how dose alternating current and direct current affect heating, ventilation, and air conditioning
What is a DC light bulb?
It is a light bulb that runs on direct current which is current that is steady unlike alternating current that switches every fiftieth or sixtieth of a second. However, this distinction is not important on incandescent bulbs since they can be powered in either direction. When heating a coil of wire, it doesn't matter if the current only flows in one direction (DC) or alternates. The only things that matter are the voltage and amount of current available.
What happens to rate of diffusion on heating?
On heating the rate of Diffusion increases..
What effect of current is utilised in bulb?
Heating effect of electric current.
What is filament current?
The current supplied to the filament of an electron tube for heating.
What do you mean by heating and magnetic effect of electric current?
When electric current travels through a conductor, there is always resistance. This resistance causes some of the energy of the current to express as heat. Additionally, the movement of the current causes a magnetic field to form around the current in a clockwise direction. This principle is what allows coil heaters and induction motors to operate.
How does current formed?
from the uneven heating of earth
