Physics for IGCSE & O level - Electricity (Section 9 - No. 7)
If the voltage across a resistor is doubled, and the resistance remains the same, what happens to the current?
It halves.
It doubles.
It remains the same.
It quadruples.
Shpjegimi
According to Ohm's Law (V=IR), if voltage doubles and resistance remains constant, current must also double.
