A circuit with two or more loops What is a parallel circuit?
Shape: Temperature is constant, so resistance is constant I-V graph for an ohmic conductor:
Explain it's shape:
Shape: As the current increases, the temperature of the filament in I-V graph for a filament bulb:
creases, which makes the resistance increase Explain it's shape:
A diode only allows current to flow in one direction. It has a very hi I-V graph for a diode:
gh resistance in the reverse direction What does it do?
Its resistance decreases if the light intensity increases What does an LDR (light-dependent-resistor) do?
