i am doing a simple audio mod that calls for 1.5k .25 watt 5% tolerance
resistors. I have 1.5k but most of them are .5 or 1 watt and 1% tolerance. could i use these? can higher watt and lower tolerance values be substituted? |

The only disadvantage of higher power resistors is that they are physically larger so they may not fit in tight spots. There is no real disadvantage of using resistors with tighter tollerance than the ones specified. |

What do you think it is? |

sorry, it is obvious (after reading up on definitions of tolerance and
watts..total newbie here) sometimes things that seem obvious are not always so, (maybe not in electronics but definitely in other facets of life). in this case i guess that adage doesn't apply. if only everything else were that simple : ) |

Also, you have a perfect right to wonder whether any "non-ideal" properties of a resistor are involved. For example, in high-frequency circuits, the inductance of the resistor (which is normally of no concern at all) might be different for a 1/4-watt than for a 1/2-watt resistor, and I can imagine designing a circuit that performs differently with one than with the other. Inductance is a "non-ideal" property of resistors since a perfect resistor wouldn't have any. Also, a more familiar example is electrolytic capacitors, which are rated for a maximum voltage, but they don't work very well if the actual voltage is too far below the maximum (like a 100-volt capacitor in a 1-volt circuit). |
