hey guys i wanted to know how to calc the type of resistor needed for certain things.
I have notice a lot of resistors burning up from stupid ol' me not putting the right resistor on it.
If i have a circuit that uses 5v @ 1A what kind of resistor should i use ? like i have seen .25, .5, .75, 1watt resistors.
I also notice in ohms law images :
P = VI
POWER = VOLTAGE X CURRENT
5Watt = 5v X 1A
Would i need a 5 watt resistor if 1 amp is to flow through it without burning up?
