A) 1 A towards right
B) 0.66 A towards right
C) 0.66 A towards left
D) Zero
Correct Answer: B
Solution :
Net current \[i={{i}_{+}}+{{i}_{-}}=\frac{({{n}_{+}})\,({{q}_{+}})}{t}+\frac{({{n}_{-}})\,({{q}_{-}})}{t}\] Þ \[i=\frac{({{n}_{+}})}{t}\times e+\frac{({{n}_{-}})}{t}\times e\] \[=2.9\times {{10}^{18}}\times 1.6\times {{10}^{-19}}+1.2\times {{10}^{18}}\times 1.6\times {{10}^{-19}}\] Þ \[i=\,0.66\,A\]You need to login to perform this action.
