1. At normal temperature the resistance of tungesten wire is . Coil of two elecric heaters are made by this type of wire are connected in parallel with the electric line (220V). As a result the temperature of the coil's wire reach to . The length and diameter both of the coil wire are twice of the coil wire. (Temperature co-efficient of resistance of tungsten wire, ).
2.
Later a particle of mass charged with charge is placed at the centre of the square .
3. After analyzing the cycle given below Tasen said, it is a Camot's cycle.
Molar Gas constant
4.
Current are passing as stem through each metallic wire. amp; ; length of each wire is and .
5.
Both transistors are made by Germanium (Ge). Knee voltage of Ge is 0.3 volt.
Given, and
