The power dissipated by a diode is P = Vf x I watts, where Vf is the forward voltage drop on diode (typically 0.5 volts for silicon diode) and I is the current.

∙ 11y agosilicon has a voltage drop of about .7 so for 10 amps its 7 watts
the maximum will be related to the power available
bigger diodes will dissipate more power

How do you calculate power dissipated by an IC?
It is very critical to never exceed the input voltage of an IC to begin with. To calculate the power dissipation ( in watts) VxI (Voltage x Current) will give you power in watts.
What are the advantages and disadvantages of maximum power transfer theorem?
The Maximum Power Transfer Theorem is not so much a means of analysis as it is an aid to system design. The maximum amount of power will be dissipated by a load resistance when that load resistance is equal to the Thevenin/Norton resistance of the network supplying the power.
What is a power diode?
A Power Diode is used when a large current is involved which needs a larger junction to dissipate the heat generated. An advantage of using the Power Diode is it is able to withstand high voltage without being damaged. A disadvantage about the Power Diode is that being a large junction it is unable to stand high frequency applications.
Determine the power dissipated if the voltage supplied to a circuit is 12V and the current measured is 3A?
The power dissipated by a circuit with a voltage of 12V and a current of 3A is 36W. Watts is Volts times Amps.
What is power diode generally made from?
As that of most power devices power diode are maid from silicon material(because of its wide band gap) . but now days alloy of silicon are used like sic(silicon carbide) by ank
Limitation of operating condition in p-n junction?
the p-n junction diode will perform satisfactorily only if it is operated within certain limiting values or conditions.The are :- 1. Maximum forward current : it is the highest instantaneous current under forward bias. 2.Peak inverse voltage: 3.maximum power rating:it is the maximum power that can be dissipated at the junction without damaging it.

What is the powder transfer theorem?
In electrical engineering, the maximum power (transfer) theorem states that, to obtain maximum external power from a source with a finite internal resistance, the resistance of the load must be made the same as that of the source. It is claimed that Moritz von Jacobi was first to discover the maximum power (transfer) theorem which is referred to as "Jacobi's law". The theorem applies to maximum power, and not maximum efficiency. If the resistance of the load is made larger than the resistance of the source, then efficiency is higher, since most of the power is generated in the load, but the overall power is lower since the total circuit resistance goes up. If the internal impedance is made larger than the load then most of the power ends up being dissipated in the source, and although the total power dissipated is higher, due to a lower circuit resistance, it turns out that the amount dissipated in the load is reduced.
Is an audio signal affected by wire gauge?
Absolutely for maximum power transfer impedance's are to be matched a low wire gauge will insure that the power is not dissipated on the wire as appose in the speakers.
What are the advantages and disadvantages of maximum power transfer theorem?
The Maximum Power Transfer Theorem is not so much a means of analysis as it is an aid to system design. The maximum amount of power will be dissipated by a load resistance when that load resistance is equal to the Thevenin/Norton resistance of the network supplying the power.
What is the power dissipated by a reactive load?
No power is dissipated by a load composed exclusively of either capacitive or inductive reactance.
Why ac is more effective than DC?
because power dissipated in ac is less than power dissipated in dc.
What is spare dissipated heat used for?
dissipated heat is used to boost the power and to combine with it
Can a diode power a circuit?
An ordinary diode, no. It has nowhere to get energy from.But a solar cell is a type of diode that converts light to electricity. So it is a diode that can power a circuit. So yes, there is one type of diode that can power a circuit.
What are the specification of diode?
The most important specifications of a diode are:maximum forward currentpeak inverse voltage (aka maximum reverse voltage)reverse leakage currentreverse turnoff time (very important in high speed switching diodes)maximum power dissipation (only given for power rectifier diodes)forward bias knee voltageparasitic capacitance (only important in high frequency applications)All of this and more can be found in the datasheet for the diode.
Why power diode has more power ratings?
It will be dissipating more power than a small signal diode.
What is the dissipated heat from the power station used for?
Dissipated heat is used to create carbon dioxide in radiators
