In a step up transformer how does the current drop if the voltage rises?
Transformers are rated in KVA, both the primary and secondary windings have the same KVA rating. (KVA is the voltage multiplied by the amperage then divided by 1000). If you have a 10 KVA step up transformer with 120V on the primary: A = 10k / 120 = 83.33A and if the secondary produces 240V: A = 10k / 240 = 41.667A
What will be the voltage 10 coils on the primary side with an input of 120 volts and 2 coils on the secondary side?
In order to determine the output voltage of a transformer, you need to specify the turns ratio between primary and secondary. You did not do that, nor did you provide any other information that could be used to deduce the output, so only a general answer can be given. The output voltage of each secondary is 10 volts (the input voltage) times the number of turns on the primary divided by the number of turns on the secondary. If, for instance, the ratio was 1:3, then the output would be 30 volts. Since there are two secondary windings, this calculation is performed independently for each secondary.
How do you calculate current capacity of transformer?
The secondary winding's current rating is the rated apparent power of the transformer (expressed in volt amperes) divided by its voltage rating (expressed in volts). This applies to both step down, and step up, transformers.
What are the two main categories secondary production can be divided?
Secondary production can be divided into manufacturing and construction. Manufacturing involves the production of goods from raw materials, while construction involves the assembly of structures and infrastructure.
What is the formula to calculate secondary current?
The secondary current is calculated by dividing the secondary current by the impedance of the load. This value shouldn't exceed the secondary-winding's rated current except for short periods of time.
Determine the secondary and primary current for a transformer which has primary voltage 1440V and secondary 240V and turns ratio of 6 if the secondary is loaded with a resistive load of 60 ohms?
An ideal lossless transformer with a primary voltage of 1440 and a secondary voltage of 240 will deliver 4 amperes to a 60 ohm load by ohms law 240 volts divided by 60 ohms causes 4 amperes to flow through the 60 ohm load. The power delivered to the 60 ohm load will be 4 amperes times the 240 volts or 960 watts. The current in the primary is divided by the primary to secondary ratio of 6. Thus, the primary current will be 4 amperes divided by 6 or 2/3 ampere. The power going into the primary will be 1440 volts times 2/3 amperes or 960 watts. In a real transformer there is losses that make the numbers change. The output voltage will be slightly less and the resistance and reactance of the windings lower the output.
What is meant by the turns ratio of a transformer?
Hi, The turns ratio depends on the amount of windings in a transformer that are needed to provide a secondary voltage/current that's different from the primary AC source. The ratio is derived from how many windings on the primary side as compared to the secondary side. Hope this helps, Cubby

How do you calculate primary current?
If it's a step up or step down transformer and you know the secondary side current, multiply the secondary current by the turns ratio. If you know the power in the secondary winding but not the current, divide the secondary power by the secondary voltage to get the secondary current and then multiply the secondary current by the turns ratio to get the primary current. The turns ratio is the number of turns on the secondary winding divided by the number of turns on the primary winding. For a step up transformer, the turns ratio will be greater then one. If it's a step down transformer, then the turns ratio will be less than one. If you don't know the turns ratio, divide the secondary voltage by the primary voltage to get the turns ratio.
Where can a full list be found showing secondary schools within the UK?
The Guardian (a news service) has a list of secondary schools in England, divided by location. Wikipedia also has a comprehensive list of school on its site.
Identify the different types of industries?
Industries are divided into two broad categories. (i) primary industries. (ii) secondary industries.
How many school grades are in Gambia?
In The Gambia, the education system is divided into several levels, including primary, junior secondary, and senior secondary education. Primary education consists of six grades, followed by three years of junior secondary and then three years of senior secondary. After completing senior secondary, students may pursue higher education or vocational training. Overall, there are 12 grades before tertiary education.
