I–V characteristics
Physics · Secondary 3 · Hard · I–V characteristics
Two resistors, A and B, have straight-line I–V graphs that pass through the origin. At 5.0 V, the current in A is 0.50 A while the current in B is 0.25 A. What does this show about their resistances?
- Resistor A has half the resistance of resistor B.
- Resistor A and resistor B have the same resistance.
- Resistor A has twice the resistance of resistor B.
- Both resistances decrease as the voltage increases.
