☑ Does Resistor Size Matter

Would a uranium 235 fuel pellet the size of earth explode. The very act of resisting current generates heat.

It only determines the resistors power handling ability.

Does resistor size matter. A small resistor will burn up if you try to push too much current through it. A capacitors size does not mean its capacitance. Contact noise is dependent on both average dc current and resistor materialsize.

That whole conservation of energy thing. The most significant contributor to noise in guitar amplifiers is the use of low wattage carbon composition resistors. So the larger a resistor the more thermal mass to radiate and the more power it can take.

In both a capacitor and a resistor size refers not only to the electrical value of the item but to its current carrying capacity. Or think about water modeling of electrical circuits. Does resistor wattage matter in this case.

A 1000 ohm resistor will measure 1000 ohms and have the same effect on current in a circuit regardless of its physical size. It refers to the physical size of the capacitor. Wiring schematic picture included ask question asked 3 years 1 month ago.

The size or surface area of a resistor is not related to its resistance. Metal film resistors however can be deceptive since a 2 watt metal film resistor will be about the size of 1 watt carbon composition resistor. The larger the resistor is the more power it can take before blowing up.

The resistor he picked is a small form factor 2w resistor. A big resistor will be able to carry a much higher current than a small one having the same resistance value. Again it does not matter which way you connect the pipe the same effect will apply.

In that model a resistor is a narrower pipe that slows the flow of water down. This can have non obvious effects as the case size of a capacitor can affect its electrical properties. This resistor is the same size as a full size 1w resistor and has the exact same thermal dissipation as a 1w resistor.

All resistors are going to vary in size because of what they are made from and how they are made. Since the noise is proportional to resistor size the use of 2w carbon comp resistors will improve the performance over that of 12w resistors. What size wattage resistor do i need for this project.

It doesnt matter which direction you are going you will have to slow down anyway. The resistor in first post continuously dissipates 09w on that gottlieb display board.
