  4. Alternating current - Wikipedia

    en.wikipedia.org/wiki/Alternating_current

    An alternating current of any frequency is forced away from the wire's center, toward its outer surface. This is because an alternating current (which is the result of the acceleration of electric charge) creates electromagnetic waves (a phenomenon known as electromagnetic radiation).

  6. Electromagnetic propulsion - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_propulsion

    Electromagnetic propulsion (EMP) is the principle of accelerating an object by the utilization of a flowing electrical current and magnetic fields.The electrical current is used to either create an opposing magnetic field, or to charge a field, which can then be repelled.

  7. Acceleration voltage - Wikipedia

    en.wikipedia.org/wiki/Acceleration_voltage

    The acceleration voltage is an important quantity for the design of microwave cavities for particle accelerators. See also shunt impedance. For the special case of an electrostatic field that is surpassed by a particle, the acceleration voltage is directly given by integrating the electric field along its path.

    An acceleration clause is a section of a mortgage contract that can have big consequences: Namely, it can require you to pay off your entire mortgage at once. Even if you miss only one payment.

  9. Speed of electricity - Wikipedia

    en.wikipedia.org/wiki/Speed_of_electricity

    Without the presence of an electric field, the electrons have no net velocity. When a DC voltage is applied, the electron drift velocity will increase in speed proportionally to the strength of the electric field. The drift velocity in a 2 mm diameter copper wire in 1 ampere current is approximately 8 cm per hour. AC voltages cause no net movement.
