Can anyone tell me that Ohm law apply on Transformer or not?

In summary, Ohm's law can be applied to transformers to calculate the voltage and current in each winding. However, there are limitations to its application, as it assumes constant resistance and does not account for inductance and capacitance. It cannot be used to determine the efficiency of a transformer, but it can be useful in troubleshooting issues by measuring voltage and current on each side. Other factors should also be considered when troubleshooting transformer problems.

Memorize ohms law and all of the variations. If you are going into the electrical field it is the mother of all laws and applies to everything.

I misread your original thread and thought you said transistor but my earlier statement is still true but a transformer is an inductor and then other considerations have to be taken into account and not the least of which is X sub L.

Question: Can anyone tell me that Ohm law apply on Transformer or not?

Ohm's law applies to everything. In addition, other equations describe the inductive nature of transformers, and transformer action.
 

1. Does Ohm's law apply to transformers?

Yes, Ohm's law can be applied to transformers. It states that the voltage (V) across a conductor is equal to the current (I) flowing through it multiplied by its resistance (R). This principle can also be applied to the primary and secondary windings of a transformer.

2. How is Ohm's law used in transformers?

In transformers, Ohm's law is used to calculate the current and voltage in each winding. By knowing the voltage and current on one side of the transformer, the law can be used to determine the voltage and current on the other side.

3. Are there any limitations to applying Ohm's law to transformers?

Yes, there are some limitations to applying Ohm's law to transformers. It assumes that the resistance of the transformer windings is constant, which is not always the case. Additionally, it does not take into account factors such as inductance and capacitance, which can affect the behavior of a transformer.

4. Can Ohm's law be used to determine the efficiency of a transformer?

No, Ohm's law cannot be used to determine the efficiency of a transformer. Efficiency is a measure of how much of the input power is converted to output power, and it takes into account factors such as losses due to heat and magnetic flux. Ohm's law only applies to the relationship between voltage, current, and resistance.

5. How can I apply Ohm's law to troubleshoot transformer issues?

Ohm's law can be a useful tool in troubleshooting transformer issues. By measuring the voltage and current on each side of the transformer, you can determine if there is an issue with the windings or if the transformer is functioning properly. However, it is important to keep in mind the limitations of Ohm's law and to also consider other factors that may be affecting the transformer's performance.
