Secondary voltage on transformer

In summary, the conversation discusses a transformer with a 5:1 turns ratio and the potential for 120v AC on the primary winding to produce 24v AC on the secondary winding. The discussion also mentions the importance of having sufficient inductance in the primary winding to avoid damaging the transformer, and provides a rough guide for the number of turns needed for each volt.

120 v ac primary and turn ratio of 5:1 I came up with 600v ac is this wrong

Which is the 5 and which is the 1?
 
  • #3
5:1 ratio on secondary 120v ac primary x5 /5 = 24v secondary

Sorry, I don't understand. Is your question answered? If so, great. If not, I still don't know whether the primary has 5X more turns than the secondary or vice-versa.

If you had a transformer which had two windings with a turns ratio of 5 times as many turns on one winding as the other, and you connected 120 volts across the larger winding, you could get 24 volts across the smaller winding.

If you connected them the other way around, you might get 600 volts.

A complication you need to know about is that the winding with 120 volts across it needs to have enough inductance to stop a large current flowing in that winding.
Otherwise, the transformer could be destroyed.
A rough guide for small transformers is that there should be about 5 turns of wire for each volt put across the winding.

So you can't just have 5 turns and 1 turn and have it work at 120 volts.

FAQ: Secondary voltage on transformer

What is secondary voltage on a transformer?

The secondary voltage on a transformer refers to the output voltage of the transformer, which is produced by the secondary winding. This voltage is typically lower or higher than the primary voltage depending on the design of the transformer, and it is used to power electrical devices.

How is secondary voltage determined on a transformer?

The secondary voltage on a transformer is determined by the ratio of the number of turns in the secondary winding to the number of turns in the primary winding. This is known as the turns ratio, and it is typically marked on the transformer. For example, a transformer with a turns ratio of 2:1 will have a secondary voltage that is half the primary voltage.

Can the secondary voltage on a transformer be adjusted?

Yes, the secondary voltage on a transformer can be adjusted by changing the number of turns in the secondary winding. This can be done by physically altering the transformer or by using tap connections, which allow for different points on the winding to be used, resulting in a different secondary voltage.

How does the secondary voltage affect the power output of a transformer?

The secondary voltage is directly proportional to the power output of a transformer. This means that a higher secondary voltage will result in a higher power output, and vice versa. However, it is important to note that the power output is also affected by other factors such as the quality of the transformer and the load connected to it.

What happens if the secondary voltage on a transformer is too high or too low?

If the secondary voltage on a transformer is too high, it can damage the electrical devices connected to it. On the other hand, if the secondary voltage is too low, the devices may not receive enough power to function properly. It is important to ensure that the secondary voltage is within the appropriate range for the devices being powered by the transformer.
