Ok Take the following facts:

Nominal Resistance = 360 Ohms
Tolerance = 5%
Maximum Permissible Resistance = 378 Ohms
Minimum Permissible Resistance = 342 Ohms

Now Assuming the resistor above is rated at 2 watts, what is the maximum continuous Voltage that can be placed across the resistor without causing it to overheat?

How do we find this?

If anyone can help, It wouldl be greatly appriciate it. Thank You
