2W Resistors Popular Q&A
Q: Does that mean that a 1/2w resistor is needed for this project?
A: P = E²/R = 144/330 = 0.44 watt. correct. Actually I'd use a 1 watt resistor. You should always derate by a factor of 2, as the rating is for the resistor in the... Read More »
Q: B. what is the minimum wattage rating of the chosen resistor if ¼...
A: The guy above is wrong. You need 8v running into the light bulb so you would use the same formula but with 8v instead of 4v that is inadequate voltage for the b... Read More »
Q: Technology Whats the difference between a 1/2w resistor and a 1/...
A: I am in need of a 33ohm 1/4W resistor. The closest I can find is a 33ohm 1/2w resistor. the source voltage is 6v, the leds(2) 2.6V each with a 28 MA current. Is... Read More »
Q: Resistor is rated at 1/2w what is the value of the limiting curre...
A: Answer 1. By definition, power rating is the maximum amount of power that the resistor can dissipate before it gets destroyed. Power and resistance are related ... Read More »
Q: If each resistor is rated 1/2 w (max without overheating) what is...
A: Well. 1. first you need to identify the equivalent resistance of the parallel combination of 2.8k ohm and 2.1k ohm. (hint: less than 1.5k ohm) 2. Now, combine t... Read More »
