GORHAM— Question: Five 2.5 mega-ohm resistors are parallel in a circuit. What is their equivalent resistance in mega-ohms?

Don’t feel like a dunderhead if you don’t know the answer, never mind what a mega-ohm is.

The question also stumped the best science and math students at Falmouth and Windham high schools Saturday morning at the 13th Maine Regional Science Bowl at the University of Southern Maine.

Eighty-five students on 17 teams from 11 high schools around the state are competing for a trip to Washington, D.C., next month to face off against other states at the National Science Bowl competition.

The free event, which continues until 3 p.m., pits students against one another in a “Jeopardy” TV game show format. The competition is fierce. It grows as the day continues and the weakest teams are winnowed out.
