I have a resistor that I need to replace that looks like this (4-color band resistor that is significantly bigger than the others):
If I read the colours correctly (brown / black / gold / gold) this should be a 1 Ω resistor, but it is considerably bigger than the normal resistors.
- Is this due to it being a higher wattage?
- Can one somehow derive the wattage by looking at the size of this resistor?
- Does the fact that it is grey also mean anything?
