Circuit Lab Flashcards

Front

Definition of voltage (V or E for EMF).

Back

Voltage is the electric potential (push) per unit charge. It is measured relative to a reference (ground). Units: V (volt).

Front

Ohm's Law formula.

Back

Ohm's Law: V = I \times R

Front

Water pump analogy for voltage.

Back

Voltage is like pump pressure (potential).

Front

Scoring breakdown for Circuit Lab event.

Back

Written test accounts for 50–75% of the score, and hands-on tasks account for 25–50%. Ties are broken by the written test.

Front

Units for current.

Back

Current is measured in amperes (A).

Front

Units for resistance.

Back

Resistance is measured in ohms (Ω).

Front

Ball-bearing tube: signal/effect propagates quickly though individual charge carriers drift slowly.

Back

Ball-bearing tubes allow signals or effects to propagate quickly, even though individual charge carriers move slowly.

Front

Formula for Coulomb's Law.

Back

Front

Capacitor function.

Back

A capacitor stores charge and resists changes in voltage.

Front

Reverse recovery time is the time to stop conducting on switching.

Back

Diodes have a reverse recovery time, which is the delay in stopping conduction when switching.
