What did the 'P.G.' stand for in the name of the writer P.G. Wodehouse? And what's a Wheatstone Bridge used for in an electrical circuit?
Brain of Britain returns to Media City in Salford for another heat featuring competitors from the North of England. This week's four contestants come from Westhoughton in Lancashire, Nuneaton, Derby and Haydon Bridge in West Yorkshire. They compete for a place in the semi-finals of this 60th season of the time-honoured general knowledge quiz.
Russell Davies is in the questionmaster's chair, and he'll also be selecting a pair of questions mailed to Brain of Britain by a listener, hoping to confound the combined brainpower of the contestants in order to win a prize.
Producer: Paul Bajoria.
