However voltage spikes can also have more mundane causes such as a fault in a transformer or higher-voltage (primary circuit) power wires falling onto lower-voltage (secondary circuit) power wires as a result of accident or storm damage. Voltage spikes may be longitudinal (common) mode or metallic (normal or differential) mode.
TV pickups occur during breaks in popular television programmes and are a surge in demand caused by the switching on of millions of electric kettles to brew cups of tea or coffee. Kettles in the UK are particularly high powered, typically consuming 2.5–3.0 kW and create a very high peak demand on the electrical grid.

[ 1 ] The switchover process is being accomplished on different schedules in different countries; in some countries it is being implemented in stages as in Australia, Greece, India or Mexico, where each region has a separate date to switch off.
The braking effect is critical to speaker design, in that designers leverage it to ensure the speaker stops making sound quickly and that the coil is in position to reproduce the next sound. The electrical signal generated by the coil travels back along the speaker cable to the amplifier.
