The primary coil of a transformer has N1 = 320 turns, and the secondary coil has N2 = 2 240 turns. If the input voltage across the primary coil is Δv(t) = 170 cos ωt, where Δv is in volts and t is in seconds, what rms voltage is developed across the secondary coil?

The rms voltage across the secondary coil is 841.47 V

Explanation:

Given data:

N₁ = primary turns = 320

N₂ = secondary turns = 2240

From the input voltage

V₁max = 170 V

The rms primary voltage is:

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
