網頁2016年5月30日 · When the voltage is stepped down, the energy doesn't just disappear. It "transforms" into higher amperage similar to a gear ratio change where you're trading speed for torque and vise versa. – user148298 Oct 21, 2024 at 4:34 For (apparent) power, see David Guerra's comment. – greybeard 2 days ago Add a comment 0 網頁2024年5月14日 · A step-down transformer converts the primary voltage level to a lower voltage across the secondary output. This is achieved by the ratio of primary and secondary windings. For step-down transformers the number of windings is higher across the primary side than the secondary side.

The output is used to power a 2,000 W kettle. Calculate the current flowing in the primary coil. \ [P_2 = V_2 \times I_2\] \ …
網頁The generator output voltages are stepped up, using transformers, for efficient transmission through the National Grid cables, to voltages of 400kV, 275kV and 132kV. The parts of the system carrying electrical supplies at voltages in … 網頁2024年4月12日 · Of these types, step up transformers produce output voltages greater than their input, while step down devices produce smaller outputs relative to their input. The two images below illustrate examples of step up and step down transformers. Note that in both cases the output voltage varies proportionately to the number of coil windings.
網頁2024年9月12日 · If the voltage is stepped up, the current is stepped down, and vice versa. Finally, we can use is(t) = vs(t) / Rs, along with Equation 15.7.1 and Equation 15.7.3, to obtain vp(t) = ip[(Np Ns)2 Rs], which tells us that the input voltage vp(t) “sees” not a resistance Rs but rather a resistance Rp = (Np Ns)2 Rs.
