The power rating for a resistor can be measured by using the standard equations which are given below. The power rating can be rated in watts or W and it is the units of power. Usually, if the resistor size is larger, then the resistor can handle more power. When the wattage of the resistor enhances then the cost will be increased.
Usually, if the resistor size is larger, then the resistor can handle more power. When the wattage of the resistor enhances then the cost will be increased. Generally, this rating ranges from 1/8th watt to kilowatts. The electrical power units with values, symbols, and abbreviations are given in the following table.
The common trait of all power resistors is that they are built to dissipate as much power as possible, while keeping their size as small as possible. In general they have a power rating of at least 5 W. Power resistors are made from materials with a high thermal conductivity, allowing efficient cooling.
The flow of current throughout a resistor can be done because of the existence of voltage across it, so electrical energy can be lost through the resistor in heat form. The flow of current is higher; the resistor will get heat more which is known as the power rating of the resistor.
Generally, resistors are rated by their resistance value and the electrical power can be given in watts. Based on resistor size, the electrical power is dissipated securely. Every resistor includes a maximum power rating which can be determined through its size.
