☑ Find Resistor Wattage Rating

Resistors can have wattage ranges that start from 003 watts to kilowatts and higher. The more watts a resistor can handle the larger and more expensive the resistor is.

What is the power rating of a resistor.

Find resistor wattage rating. 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. With wirewound and other power resistors the wattage rating is usually stamped on the resistor body. Most resistors are designed to handle 18 w or 14 w.

When a circuit does not exceed the power rating the resistor works reliably and without fuss for decades. The power rating of a resistor is the specification given with a resistor that serves to tell the maximum amount of power that the resistor can withstand. A 1 watt resistor will be larger than a 14 watt resistor.

Power is measured in units called watts. The power rating of a resistor indicates how much power a resistor can handle before it becomes too hot and burns up. In addition to a resistance value measured in ohms it has a maximum power rating measured in watts.

I assumed your supposed to use ohms law and i got 4608 watts as the minimum number of rated watts. Find the power dissipated by each resistor and note whether the power delivered is equal to the dissipated d. If the resistors available with wattage rating of 1 and 2 w what is the minimum wattage rating can be used for each resistance.

Verify kvl around closed loop c. Every resistor has a maximum power rating which is determined by its physical size as generally. A resistor is a standard electronic component that has a constant electrical resistance in a circuit.

It asks to find what the minimum number of rated watts a series resistor must be if it has 48 volts dropped across it and has a resistance of 5 ohms. Find the total resistance current and unknown voltage drops b. The following drawing and table give an indication of the dimensions of common carbon film and metal film axial resistors.

This is known as the resistor power rating. Thus if a resistor has a power rating of 14 watts 14 watts is the maximum amount of power that should be fed into the resistor. Resistors are rated by the value of their resistance and the electrical power given in watts w that they can safely dissipate based mainly upon their size.

With carbon composition obsolete and carbon film resistors the physical size of the resistor is proportional to its wattage rating. Furthermore the size of an axial resistor depends on the power rating and the type of resistor such as carbon composition wirewound carbon or metal film.
