Resistors are assigned a power rating. if the power rating is exceeded significantly, the resistor will overheat and crack. suppose you have a 11 kω, 0.4 watt resistor. what is the maximum voltage it can safely handle (volts)?

The Maximun voltage is 66.33 volts.

Explanation:

According to the statement the power rating is 0.4 watt. we have to find a voltage that give us that power so we can set that value as a limit.

according with Ohm's law

(1)

and

(2)

if we sustitute (1) in (2)

So the voltage that gives a power of 0.4 watt is given by:

so 66.33 is the limit, if we apply a voltage greater than 66.33 the resistor will overheat and get destroyed.
