Frequently asked questions
Can I use this 1/4 W resistor where more power is dissipated?
No. A 1/4 W (0.25 W) resistor overheats if it dissipates more than 0.25 W. Calculate the power using P = I²R or P = V²/R for your circuit and choose a higher wattage resistor if needed.
How can I confirm the 4.3 Ω value before using it?
Read the colour bands with a resistor colour code chart, or measure the resistance with a multimeter in resistance mode while the resistor is out of the circuit.
