What is the ratio of the distance across corners to the distance across flats of a regular hexagon?
nothing
How do you use pi to find a circle?
pi is the ratio of a circle's diameter (the distance across it) to its circumference (the distance around it).
What is the ratio of stride length to height?
The ratio of stride length to height typically ranges from about 0.4 to 0.5 for most individuals, meaning a person's stride length is approximately 40% to 50% of their height. This ratio can vary based on factors such as walking speed, fitness level, and individual biomechanics. Taller individuals usually have longer strides, but the ratio remains relatively consistent across different heights.
What is the ratio of boys to girls being born?
Across the world, very close to 1. However, there are major deviations from that in countries such as India and China - although the reasons are different.
How do you find the constant of proportionality or ratio of n to m in a triangle?
To find the constant of proportionality or ratio of ( n ) to ( m ) in a triangle, you need to identify two corresponding lengths from similar triangles or a specific relationship between the sides. If ( n ) and ( m ) represent the lengths of two sides, the ratio can be calculated by dividing one length by the other (i.e., ( \text{Ratio} = \frac{n}{m} )). Ensure both sides are in the same unit of measurement for accuracy. If the triangles are similar, this ratio will remain consistent across all corresponding sides.
Is the turns ratio of transformer the same as the ratio of voltages across the transformer.why or why not?
plz give me answer the above question
How to find stator to rotor turn ratio of a slip ring induction motor?
In open circuit, find the ratio of voltages across the slip rings in rotor side to the applied stator voltage.
Does the formula used to calculate the turns ratio uses the phase voltages and phase current?
No, the turns ratio formula calculates the ratio of the primary to secondary winding turns on a transformer using the number of turns on each winding. Phase voltages and currents are not directly used in this calculation.
How are lower voltages combined into higher voltages for transmission?
Low voltages are not 'combined into higher voltages' for transmission! The lower voltage (e.g. the voltage generated at a power station) is applied to the primary winding of a large power transformer, and the required higher transmission voltage then appears across the transformer's secondary winding. The magnitude of the secondary voltage is determined by the turns ratio of the transformer's windings.
If gain is 10 db what is the ratio of voltages?
10 dB gain means a voltage ratio of 3.16227766 to 1.
How do you determine ratio if only second voltage is given?
You can't. You need to know both the secondary and the primary voltages to determine the voltage (or turns) ratio.
What is approximate turns ratio of the centre-tapped transformer used?
It depends on the voltage ratio of the transformer. If you know the primary and secondary voltages, then you can work it out for yourself.
How do you determine transformer turns ratio if the supply source and load is given?
Transformer turns ratio is the ratio of voltages between two windings. For instance, a 24VAC control transformer that runs on 120VAC will have a turns ratio about 5 to 1.
What is voltage ratio on a transformer?
The voltage ratio of a potential, or voltage, transformer (PT or VT) depends upon the primary voltage to which it is connected. Accordingly, its voltage ratio varies considerably, as there is huge variety of system voltages throughout the world.Typically a VT's secondary voltage is standardised at 110 V which will match the full-scale deflection of a voltmeter connected to it (although it can also supply protective relays), while its primary voltage is then matched to the voltage of the system to which it is connected: in the UK, for example:11-kV:110 V33-kV:110 Vetc.
How does a voltage divider work to distribute voltage across multiple components in a circuit?
A voltage divider is a circuit that uses resistors to divide the input voltage into smaller voltages across multiple components. This is achieved by connecting the resistors in series, creating a voltage drop across each resistor based on their resistance values. The output voltage across each component is determined by the ratio of its resistance to the total resistance in the circuit.
How do you explain current in Ohm's Law?
I=V/R, current = voltage divided by resistanceAnswerOhm's Law states that 'the current flowing through a conductor, at constant temperature, is directly proportional to the potential difference across the conductor'.Ohm's Law only applies when the ratio of voltage to current is constant over a wide range of voltages. If the ratio changes, then Ohm's Law does not apply.
Is the turns ratio of transformer the same as the ratio of voltages across the transformerwhy or why not?
In general the turns ratio is equal to the ratio of voltages. A few turns might be added to the secondary to provide extra voltage to offset the voltage drop caused by the resistance of the secondary when the transformer is supplying a load.Another AnswerFor an 'ideal' transformer, the answer is yes, and the reason is based on the e.m.f. equations for a transformer which, for the primary winding is: Vp = 4.44 Np f x flux ...and, for the secondary winding is: VS = 4.44 NS f x fluxSince the frequency (f) and flux is common to both windings, dividing one equation by the other will result it:VP/VS = NP/NSSo, as you can see, the voltage ratio and the turns ration are the same.
