A power adapter for a video games console includes a transformer.
The primary voltage VpV_{\text{p}}Vp to the transformer is 230 V230\text{ V}230 V.
The number of turns on the primary coil NpN_{\text{p}}Np is 460460460 turns and the number of turns on the secondary coil NsN_{\text{s}}Ns of the transformer is 242424 turns.
Calculate the secondary voltage VsV_{\text{s}}Vs of the transformer.
The plug connecting the adapter to the mains supply contains a fuse.
Describe how a fuse protects the circuit when a fault causes the current to become too large.
