WebThe aim of the high voltages in the National Grid is to produce a low current for a given amount of power delivered to the consumer. Recall that power is the energy transferred per second in Watts. A home in the UK for example has a 15 A supply at 230 V AC voltage. As Power = Current x Voltage 15 x 230 = 3,450 Watts for a domestic supply. WebThe loudspeaker uses a coil which can. slide backwards and forwards over the central pole. of a circular permanent magnet. The coil is. joined by the brown bars to a paper cone, shown below. The wire from the amplifier carries an alternating current. which makes the coil (and the paper cone) move. backwards and forwards at the same frequency.
