The ohms tells you the resistance; the wattage tells you how much heat energy it can handle. Not that any resistor ever lived up to its specifications -- I always needed some type of heat sink. Bottom line -- yes.
cause its bad,replace with higher wattage rating.too much current !!
Resistors are rated in wattage so the lowest wattage rating will be the wattage of the series circuit. It will be able to handle that power any more and the lowest wattage resistor could be damaged and fail.Another AnswerWhen two or more resistors are connected in series, the resistor with the lowest resistance will operate at the highest power. If the power developed by a resistor exceeds its rated power, then the resistor may burn out.
You should not use a higher wattage bulb in a lamp that says 40 watts. The higher wattage could cause the lamp to catch fire due to the excess heat and could cause you serious electrical problems.
it can't handle more power than that rated wattage. exceed the rating and it burns out.
How much power it can dissipate without being damaged.
Not recommended you might start a fire.
there might be ways to get the power rating by measuring the size of the resistor. but as the physical size of the resistor increases, its power rating also increases..
If your batteries were in series the total voltage would be 6 volts, and it the bulbs were in series you would need a resistor to keep them from burning out. In order to know how many ohms the resistor would need to be you would have to know the wattage of the bulbs, or the resistance of the bulbs. If you don't know the best thing to do is use a variable resistor. Then you can adjust it or the brightness that you want.
The wattage rating of a timer is governed by the manufactures specification. As long as the light bulbs wattage rating is not higher than the timers rating, the timer will be alright to use in the circuit. The circuits load is what governs the wattage of the circuit.
LED's are light emmitting diodes. diodes have a voltage threshold that must be reached for them to fully "turn on". A resistor can be used to limit that voltage. As the voltage drop across the diode is increased above the turn on voltage (typically .5 - .7 volts), the diode will emmit light. The LED will only light up so far, so by turning the voltage up significantly more will have a very limitted payback in light output.
Wattage.
You can use a lower wattage bulb on a higher wattage fixture provided the voltage rating is the same and the bulb base is the same.
