The Resistor Wattage Calculator helps you determine the power dissipation and resistance of a resistor based on the voltage across it and the current flowing through it. Power dissipation in a resistor is a crucial factor to consider in circuit design to ensure that the resistor can safely handle the electrical power without overheating.
P = 5V × 0.05A = 0.25W With a safety factor of ×2: Use a 0.5-watt or preferably a 1-watt resistor. The resistor power rating is the maximum power a resistor can dissipate without overheating. Common ratings include: Always select a resistor with a power rating above the calculated dissipation to avoid thermal stress.
Hence a 1/4th watt resistor must be used here. Using 1/8th watt resistor will damage the circuit. Resistors that are designed to handle high power are called power resistors. Resistors with power rating of at least 5W come under power resistors. The material used for construction of power resistors must be of high thermal conductive in nature.
We know V= 12v ,R=800 ohms.Now calculating the current I=V/R=12/800 = 0.015=15 mA current. Thus power dissipated by the resistor is calculated using P= 12x15x10 -3 =0.18 watts Hence a 1/4th watt resistor must be used here. Using 1/8th watt resistor will damage the circuit.
