A 240volts is applied to a primary coil of a step up transformer. What is the ratio of the secondary turn to the primary turns, if the voltage available at the secondary coil is 360volts.?
360:240 = 3:2
Ns/Np = Vs/Vp.
Ns/Np = 360/240 = 3/2.
To find the ratio of the secondary turns to the primary turns in a step-up transformer, you can use the formula:
Secondary Voltage / Primary Voltage = Secondary Turns / Primary Turns
In this case, we have a primary voltage of 240 volts and a secondary voltage of 360 volts. Plugging these values into the formula, we get:
360 / 240 = Secondary Turns / Primary Turns
Simplifying the equation, we have:
3/2 = Secondary Turns / Primary Turns
To find the ratio, we can multiply both sides of the equation by 2 to eliminate the fraction:
3/2 * 2 = (Secondary Turns / Primary Turns) * 2
3 = 2 * (Secondary Turns / Primary Turns)
Then, we can divide both sides of the equation by 2 to isolate the ratio:
3 / 2 = (Secondary Turns / Primary Turns)
Thus, the ratio of the secondary turns to the primary turns is 3:2, or simply 3 is to 2. This means that for every 2 turns in the primary coil, there are 3 turns in the secondary coil.
