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?

15 $Omega$

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,

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

$R_2=(24*5)/8$

$R_2= 120/8$

$R_2 =15$ $Omega$
