text: Self-heating occurs as power is dissipated by the resistor in response to current flowing through the resistor.
text: The above power triangle is great for calculating the power dissipated in a resistor if we know the values of the voltage across it and the current flowing through it.
text: This causes excessive power to be dissipated in the resistor which makes it go up in flames and a cloud of smoke as this video shows.
text: If the average power dissipated by a resistor is more than its power rating, damage to the resistor may occur, permanently altering its resistance; this is distinct from the reversible change in resistance due to its temperature coefficient when it warms.
text: A 3rd equation -> P = V.I can also be used to calculate power dissipated across a resistor.
text: Therefore, to calculate the power dissipated by the resistor, the formulas are as follows:
text: So, using the above circuit diagram as our reference, we can apply these formulas to determine the power dissipated by the resistor.
text: Power dissipated by the resistor = I^2 * R or V^2 / R, where R = its resistance value, I = the current in the resistor, and V = the voltage drop across the two terminals of the resistor.
text: Power dissipated in a resistor can be calculated by knowing either voltage across the resistor or current through the resistor.
text: The power dissipated in a resistor goes into heating the resistor; this is know as Joule heating.
text: The power that is dissipated in the resistor is calculated by multiplying the voltage across the resistor by itself and then dividing that result by the value of the resistor.
text: The equation for calculating the power that is dissipated in the resistor is:
text: and the power dissipated by a resistor is
