Power in resistor calculator. The power p in watts w is equal to the squared voltage v in volts v divided by the resistance r in ohms w. The power p in watts w is equal to the voltage v in volts v times the current i in amps a. Resistors can allow only a limited current amount passing through themonce the current passes through the resistor it produces heatif the heat is too great then the resistor will burn down.

What does this calculator do. 1j 1n m 1w s. Resistors can have wattage ranges that start from 003 watts to kilowatts and higher.

The bottom one calculates power dissipated in a resistor given the current flowing through it. The resistor power rating is sometimes called the resistors wattage rating and is defined as the amount of heat that a resistive element can dissipate for an indefinite period of time without degrading its performance. These calculators perform calculations associated with power wattage.

Pulse energy table pulse power table. Even if the formula for dc heat dissipation in a resistor isnt at your fingertips a little ohms law and the definition of power can easily create it. Calculate power from voltage current p v i.

The resistor color code calculator decodes and identifies a value and tolerance of 4 band wire wound resistors. Products smd power metal strip pulse calculator smd power metal strip pulse calculator. Calculates voltage current resistance power.

Ohms law calculator online. Compared to other calculators we have posted this one is extremely simple. Electric energy is e p t measured in watt hours or also in kwh.
