Electric Current (Junior Cert Engineering): Flashcards

Flow of electrons through a conductor

Negative to positive terminal

Materials that allow current to flow freely

PVC, acrylic, wood, rubber, mica

Volts (V)

$V = I \times R$

Ohms ($\Omega$)

In series

In parallel

Same through all components ($I = I_1 = I_2$)

Same across each branch ($V = V_1 = V_2$)

Protects circuits from too much current

50 Hz

Current, voltage, and resistance

Whole circuit stops working
