SHOCK VALUE
• Competition must have at least one task or
question from each of the five areas.
• Competition must consist of both hands-on
tasks and questions.
• 50% of the score must be from hands-on tasks
and 50% must be from the theoretical portion.
• The event supervisor may provide some
mathematical relationships.
• Topics not included in the events are
semiconductors, AC circuit theory and devices,
capacitors, or inductors.

Competition Format
• There are two competition times:
one for Even and the other for the Odd
numbered teams (12 or 13 teams are
competing in each time slot).
• The competition will consist of six to seven
stations through which the teams rotate.
• There are at most two teams working at each
station.
• Each station focuses on one of the five areas.
• Teams have about 6 minutes (depending on
the number of stations) at each station. They
are not permitted to return to a station.

Ohm’s Law
Ohm’s law states that current is inversely
proportional to
resistance
How much current flows through a lamp
that has a resistance of 60 ohms when
12 V is connected across it?
I = V/ R
I = 12 V / 60 ohms = 0.2 amps
