a) Heat produced or absorbed at a junction is proportional to the current by the junction.
b) This effect is produced when current is passed by junction of suitable materials.
c) It is reversible effect.
d) Heat exchange depends upon nature of conductors and temperature of the junctions.
e) It can be heating as well as cooling effect.
What are the basic reasons for loss of residual magnetism? How do you get it? What is the requireable and maximum DC voltage is to be applied to get back the residual magnetism?
When current is passed by a junction of two dissimilar solids, the temperature is either evolved or absorbed at the node. This effect is known as Peltier effect
how much energy is required to raise an object of 300g that is initially at rest to a height of 2m and simultaneuosly give the object a velocity if 4m/s?
Sliding versus Static Friction: Friction force is the force exert by a surface as an object moves crosswise it or makes an effort to move across it. Two types of friction force
Q. Define: optic axis of a crystal. In a double refracting crystal there is a particular direction in which both the rays travel with same velocity. This direction is called a
Que: In the circumstances of charge distributed on a line segment what do we mean by the expression linear charge density λ(x)? Note that λ(x) is to be study lambda of x mea
what is Friction When we think about friction, there is one more place for energy to go - heat. When you push a book across a table, does the energy of the book change? Not if in
