      @zareen said in PHY301 GDB 1 Solution and Discussion:

      what types of charges are responsible for flow of current in each matter?

      Insulators and conductors can be solid, liquid or gas, and in some exceptions like glass (solid) which is an insulator becomes conductors when melted at the higher temperature. On the other hand, semiconductors are present in the solid form.

      Liquids can be conductors or insulators, depends on other properties. Though absolute pure water is an insulator, the liquid metals are electrically conductive. Gases also become electrically conductive when ionized, though they usually are insulators.

      Conductivity is the phenomenon of transmitting something like heat, electricity or sound. So, based on the conductivity of any material and the presence of a forbidden gap, they (materials) can be classified as conductors, semiconductors or insulators. In the article, we will be differentiating the three terms concerning other points on which they vary.

      Q. 1 Solution:
      Starting from lower side of circuit network, we can see that 2Ω and 2Ω are in series, so their combined effect is
      2+2=4Ω
      97b5d636-b0d8-40d1-8f33-9266b3779585-image.png

      This 4Ω is in parallel of 4Ω to lower side, so their equivalent is

      0888b8c5-aeba-4acd-9184-9f1a8f70b1ef-image.png

      This 2Ω is in series of 5Ω and 1Ω, so the sum of series resistances is

      2Ω+ 5Ω+1Ω=8Ω

      Now at upper side, 4Ω and 2Ω are in series
      4Ω+ 2Ω=6Ω

      This 6Ω is in parallel of 6Ω, so their equivalent is

      This 3Ω is in series of 3Ω and 1Ω, so the sum of series is

      3Ω+ 3Ω+1Ω=7Ω
      051e272e-1e7b-48b8-9359-4810dcb187d5-image.png

      Now we can see 7Ω becomes in series of 8Ω, so equivalent resistance is
      Req =7Ω + 8Ω
      Req=15Ω

      Q.2 Solution:
      1)
      To calculate the source current Is, Firstly, we calculate the total resistance
      RT= R1+R2+R3
      =6Ω
      V=IR
      IS=VS/RT
      = 12/6
      =2A

      2)
      Since all resistances are in series, same 2A current pass through each resistance.
      V1= R1IS
      =12
      =2V
      V2=R2Is
      =22
      =4V
      V3=R3IS
      = 32
      =6V

      3)
      P1 =I2R1
      = (2)2 *1
      =4W
      P2 =I2R2
      = (2)2 *2
      = 8W
      P3 =I2R3
      =(2)2 *3
      = 12W
      = 12W

      4)-
      Ps = VsIs
      P =122
      =24 W
      PT=P1+P2+P3 or PT=I2RT
      =4+8+12
      =24 W
