A transformer with a primary of 1200 turns and a secondary of 400 turns has what ratio?

A transformer primary of 1200 turns with a secondary of 400 turns is a ratio of 3 to 1.


Does the ratio of voltage in a primary coil to secondary coil depends on the turn of each coil?

Yes, although the question is poorly formed. The ratio of the voltage in the primary winding to the voltage in the secondary winding is the same as the ratio of the number of turns in the primary winding to the number of turns in the secondary winding. For example, if the primary had 1200 turns with the secondary having 120 turns, and the primary voltage was 50 volts, then the secondary would be 5 volts. This is a ratio of 10:1.


Why the CT secondary short circuited?

Current transformers produce a ratio of primary current in the secondary. If the secondary of a CT is open circuited, and primary current is flowing, the CT will try to push that same ratio of current through the secondary open circuit. This causes secondary voltage to climb until it the secondary open circuit flashes over. This can often damage the CT.


If the voltage in a transformer is twelve volts and the primary coil has ten turns and the secondary coil has twenty what is the voltage across the secondary coil?

I assume the primary has 12 volts applied. The voltage ratio from primary / secondary is equivalent to the turns ratio = 10/20, so the primary voltage is 1/2 of the secondary voltage. The secondary voltage is 24.


How do you find secondary voltage with a ratio of 1 to 200?

If the primary is 1 and the secondary 200 then multiply the primary voltage by 200.

What is the ratio between boy or girl in the world?

Sex ratio denotes the ratio of males to females in a population. The primary sex ratio is the ratio at the time of conception, secondary sex ratio is the ratio at time of birth, and tertiary sex ratio is the ratio of adult human beings. According to CIA estimates the current world sex ratio at birth is 107 boys to 100 girls. In 2010 the global sex ratio was 986 females to 1000 males, which got further reduced to 984 females to 1000 males in 2011.


What is the probability of getting male and female offspring in human?

The male to female human sex ratio varies, due to demographics, environment, sex deterministic abortion, and imbalance in the male/female sperm viability ratio. The secondary ratio of boys to girls is about 105 to 100, or about 0.525 male. Estimates of the current birth sex ratio is about 0.535 male. The current global sex ratio (population) is about 0.507 male (2010) to 0.508 male (projected 2011).

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.

What are the three secondary sex glands in a cow?

There really is no such thing as "secondary sex glands" in any mammal. The sex glands, secondary or not, are the ovaries. These are what determine estrous cycles and detection of pregnancy. The hypothalamus and the pituitary glands in the brain also have to do with the reproductive cycle of a cow, but they are also not described as "secondary sex glands."

Does the ratio of voltage in a primary coil to secondary coil depends on the turn of each coil?

Yes, although the question is poorly formed. The ratio of the voltage in the primary winding to the voltage in the secondary winding is the same as the ratio of the number of turns in the primary winding to the number of turns in the secondary winding. For example, if the primary had 1200 turns with the secondary having 120 turns, and the primary voltage was 50 volts, then the secondary would be 5 volts. This is a ratio of 10:1.


What determines the voltage that is transferred from the primary to the secondary winding?

The turns ratio between the primary and the secondary.


How many turns in secondary coil in Transformer?

It depends on the type of transformer.If it is a step up transformer the number of turns in secondary side is higher than primary.Stepdown means it will have fewer number of windings on the secondary side turns when compared with the primary side.An isolation transformer has the same number of windings on the primary as the secondary.The ratio of the windings is proportional to the increase or decrease in the secondary voltage. For example, twice the windings doubles the voltage and 1/2 the windings halves the secondary voltage. The isolation transformer is denoted as 1:1 and has the same voltage on the secondary as the primary.The ratio of secondary turns to primary turns is the same as the ratio of secondary voltage to primary voltage.e.g. if the secondary to primary turns ratio is 1/10, then the secondary voltage will be one tenth of the primary voltage.
