A 2 gram Magnesium (Mg) ribbon is burnt in air . The burnt ribbon is collected and weighed. Would it be greater than 2 grams or lesser?

I would like to know what is a wheatstone bridge? I read that it is an arrangement of resistors but i am not understanding how it works and the whole concept. Any help would be appreciated. Thank You.

I get it , so the main reason is melting point! Thanks a ton , i have an exam tommorow , this will surely help!

i think it should be high melting point ( Tungsten has a MP of 3380 C) but again , it has a very low resistivity which means it has a low resistance. So according to Joule's law of heating , a very less amount of heat would be produced . What are your views on this?

Homework Statement Why is a tungsten filament used in incandescent bulbs? I earlier thought that it was due to the high resistivity of tungsten , but i was wrong , the resistivity of tungsten is low at 5.2 * 10^-8 Is it due to its high melting point?? I can't figure out as...

The left hand rule is a very simple rule to apply - 1) Stretch out the thumb , first finger and the middle finger (!) such that they are mutually perpendicular. 2) If the middle finger is pointing towards the direction of flow of current(I) , then the first finger shows you the direction of...
