Physics for IGCSE & O level - Electricity (Section 1 - No. 3)
What happens if the current flowing through a resistor increases?
The resistance decreases.
The voltage across the resistor decreases.
The power dissipated by the resistor increases.
The power dissipated by the resistor decreases.
Wyjaśnienie
Power (P) = I^2 * R; If current increases, power increases.
