Question

If on applying the potential of 20 V on a conductor its conductance becomes $8\,{{(\Omega )}^{-1}},$ then the current flowing through it will be

• A. 120 A
• B. 160 A
• C. 90 A
• D. 80 A

Answer 1

Answer: (B)

160 A

Answer 2

Conductance $\text{=}\frac{\text{1}}{\text{Resistance}}$ $\therefore$ Resistance $(R)=\frac{1}{8}\Omega$ $\therefore$ Current flowing through the conductor $I=\frac{V}{R}=\frac{20\times 8}{1}$ $=160\,\,A$
