You can't answer this question the way it is asked.

Watts are power. Watts = Amps * Volts= i*e

Ohms are resistance. Volts = Amps * Ohms ==> e = i * R

To find the number of Ohms in a resistor assuming it is dissipating a given number of Watts, you need to know either the voltage across the resistor or the current passing through the resistor.

15 watts is a product of voltage times current. Ohms are a measure of resistance in a circuit or a device. to get the current you divide the applied voltage by the resistance (ohms law). I hope this helps

None. Ohms and watts measure two different things.

According to Ohms law, P = VI, and V= IR

So, P = (IR)*I = (I^2)R

So R (ohms) = P (watts) / I (amps) squared

You would need to know the amperage.
