32: Electric Current in Conductors
- #33Find the currents through the three resistors shown in the figure (32-E9).
Figure32-E9
Ans :
From the figure, we can see that current will flow only in loop 1 because current follows the least resistive path. All the current will pass through the wire connected in parallel to the 4 Ω resistor in loop 2.
∴ There will be no current through the 4 Ω resistor in loop 2.
For loop1, applying KVL, we get:
`` 6i+4i-4+2=0``
`` \Rightarrow 10i=2``
`` \Rightarrow i=0.2\,\mathrm{\,A\,}``
`` ``
∴ The current through the 4 Ω and 6 Ω resistors, i = 0.2 A
