Mains Electricity and wiring a Plug Crossword

When wiring a [1d] you have to make sure that you connect the wires properly.

The [17a] wire goes to the [3d] connection

The [5a] wire goes to the [15a] connection and the [2a] and [12d] striped wire goes to the [9d] connection.

To make the wires secure you tighten the [14d (two words 4,4)].

In the UK we have an AC domestic supply of electrical [20a] as opposed to one from batteries which is called a [21d] supply. This AC supply varies at a frequency of 50 [16a].

The [6a (two words 5,7)] is 230V. This could be lethal so appliances with a [22a] CASE are earthed.

A [11d] is inserted in the live wire connection. This is a safety feature. If too much current flows through it, the fuse will [13d]. It does not 'explode', rather it [19d] and this makes a [26a] in the circuit. As the [24a] is no longer complete. No more current [4d] flow through [23a] appliance.

The power of an appliance is measured in [18d]. You can measure current with an instrument called an [7d] in [8d] (unit of current) and potential difference with a voltmeter in [10a] (unit of potential difference).
