W/o power going through, it won't burn out. It may shake itself to bits, corrode, or fail through other mechanical reasons. But burn out require power through it.
It depends on where you are going to use this resistor and what its application going to be. If the circuit you are using can tolerate this then you are fine.
A 30 volt 90 watt lamp has 3 amps going through it. The series resistor also has 3 amps going through it, by Kirchoff's current law. The voltage across the resistor is 90 volts. With 3 amps, that is 30 ohms. (By the way... The resistor must be rated to carry 270 watts. That is a lot of power for a resistor.)
No such resistor exists. Any resistor placed in parallel with a 6.0 ohm resistor is going to reduce the combined resistance below 6.0 ohms.
Ohm's Law: Volts = Amps * Ohms That means that you have 45 volts across the resistor. Power = Volts * Amps That means that you 3.375 Watts going through the resistor.Alternative AnswerMultiply the square of the current by the resistance.
All resistors have the same function in a hobby kit, to cause a voltage drop in series circuits or reduce currents in parallel circuits. A value of 180k ohms is just going to do that by a lot.

If you know the value of the resistor you can cut the wires going to the lock cylinder and solder in a resistor of the correct value.
It depends on the current going through it. Ohm's law: Voltage equals current times resistance.

Current passing through a resistor, et al, causes heat. The heat causes the resistance of said resistor to decrease, which causes current to increase, and the cycle just keeps going until the circuit burns out.
must be too much load going through it and blowing it out, get the wiring checked.
