How to correctly use if/else if?????? Please Help

Here is the assignment:

The current I drawn by an electrical appliance of power P watts from a supply voltage V volts is given by the formula: I = P/V amps. An electrical supplier stocks three types of cable, suitable for currents of up to 5 amps, 13 amps, and 30 amps, respectively. Write a program that asks the user for the power rating and supply voltage of an appliance, and displays the most suitable cable, or a warning if the appliance cannot be safely used with any of the cables in stock.

------------------------------------------------------------------------

I have everything set up to the best of my ability:

Code:

`#include <iostream>`

#include <cmath>

using namespace std;

int main()

{

float P,V;

cout << "Enter the power rating of the appliance: " << endl;

cin >> P;

cout << "Enter the supply voltage of the appliance: " << endl;

cin >> V;

if (0 < P/V <= 5)

{

cout << "This current is suitable for the 5 amp cable" << endl;

}

else if (5 < P/V <= 13)

cout << "This current is suitable for the 13 amp cable" << endl;

else if (13 < P/V <= 30)

cout << "This current is suitable for the 30 amp cable" << endl;

else if (P/V > 30)

cout << "This current can not be safely used with any of the cables in stock" << endl;

return 0;

}

------------------------------------------------------------------------

But when I try using my program, I get the same answer for every current (That the 5 amp cable is appropriate):

Enter the power rating of the appliance:

90

Enter the supply voltage of the appliance:

2

This current is suitable for the 5 amp cable

How do I properly use if, else if so that my program runs correctly?
