The generator at a power plant produces AC at 20,000 V. A transformer steps this up to 355,000 V for transmission over power lines. If there are 2,250 turns of wire in the input coil of the transformer, how many turns must there be in the output coil

Number of coil in the output is 39938

Explanation:

We have given a step up transformer

Input voltage of transformer, that is primary voltage

Output voltage, that is secondary voltage

Number of turns in primary

For transformer we know that

As the number of turns can not be in fraction so number of turns in the output coil is 39938

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
