Question

The current flowing in a wire is inversely proportional to the resistance of the wire. If the current is 5 amperes (A) when the resistance is 24 ohms (Ω), for what resistance will the current be 8 amperes?

Answer 1

15 `Omega`

Explanation:

We know that,

`R prop 1/I`

From above equation, it is clear that

`(R_2)/(R_1)=(I_1)/(I_2)` `---------->(1)`

From given data,

`I_1 =5 & R_1 =24`
`I_2= 8`

`R_2=(24*5)/8`

`R_2= 120/8`

`R_2 =15` `Omega`
