When AC is changed into DC to charge a laptop or phone, is the resulting voltage perfectly constant? A. Yes B. No, but it can be made pretty close C. No, in fact sometime it's negative

Would a pencil rolling off a desk be kinetic energy?

Suppose that after a certain time tl, the string has been pulled through a distance l. what is the final rotational speed ωfinal of the wheel?

The per-unit impedance of a single-phase electric load is 0.3. The base power is 500 kVA, and the base voltage is 13.8 kV. a. Find the per-unit impedance of the load if 1 MVA and 24 kV are selected as base values. b.

If the resistance in a circuit connected to a constant current is halved, how is the voltage in the circuit affected? The voltage remains constant. The voltage is doubled. The voltage is reduced by a factor of 4.
