primary and secondary coilsAnswerPrimary and secondary windings.
To determine the amount of primary current needed to supply the first secondary winding, you would typically use the transformer equation, which relates primary and secondary voltages and currents. The equation is ( V_p / V_s = I_s / I_p ), where ( V_p ) and ( V_s ) are the primary and secondary voltages, and ( I_p ) and ( I_s ) are the primary and secondary currents, respectively. By rearranging this equation, you can solve for the primary current ( I_p ) needed to supply the secondary winding based on the known values of the transformer’s voltages and the secondary current. Additionally, efficiency and losses in the transformer should be considered when calculating the actual primary current required.
A: The only way can be possible if the transformer is an isolation type. Yes, you can put the input into the secondary side. This will create a step-up transformer.
No. the primary winding is called the primary; the secondary winding is called the secondary. These are both wrapped around the iron core of the transformer. The core helps magnetically link the primary and secondary, which causes the transformation of voltage and current from primary to secondary.
The difference between the two transformers is the coil ratios between the primary and secondary windings. A transformer that increases voltage from primary to secondary has more secondary winding turns than primary winding turns and is called a step-up transformer. Conversely, a transformer with fewer secondary windings does just the opposite and is called a step-down transformer.
No, the primary winding VA does not necessarily equal the secondary winding VA when a transformer is loaded. The power output on the secondary side may differ from the power input on the primary side due to losses such as resistive and core losses in the transformer. The transformer's efficiency will determine how close the VA on the primary winding is to the VA on the secondary winding.

If the number of turns in the primary is the same as the secondary, this would be an isolation transformer. Primary and secondary voltages should match (minus the inherent transformer losses), as should the current.

When the secondary of a transformer is opened, there is no longer any load on the transformer. There will be some current flowing in the primary winding, which is needed to induce the voltage in the secondary. This primary current is referred to as the "no load" current, and is indicative of the core losses in the transformer.
No. the primary winding is called the primary; the secondary winding is called the secondary. These are both wrapped around the iron core of the transformer. The core helps magnetically link the primary and secondary, which causes the transformation of voltage and current from primary to secondary.
This isn't the case. You can have aluminium or copper on primary or secondary side of a transformer.
You will have a 1:1 ratio isolation transformer.
The difference between the two transformers is the coil ratios between the primary and secondary windings. A transformer that increases voltage from primary to secondary has more secondary winding turns than primary winding turns and is called a step-up transformer. Conversely, a transformer with fewer secondary windings does just the opposite and is called a step-down transformer.
A transformer primary of 1200 turns with a secondary of 400 turns is a ratio of 3 to 1.
Transformer step-up/step-down voltage is turns-ratio, so if a transformer has 20 primary windings and 100 secondary windings (a turns-ratio of 1 to 5) and the secondary voltage is 25, then is the primary voltage is 5.
