Physics for IGCSE & O level - Electricity (Section 3 - No. 9)
What is the relationship between power and current, given a constant voltage?
Power is directly proportional to current.
Power is inversely proportional to current.
Power is independent of current.
Power is proportional to the square of the current.
Paaiškinimas
P = V * I. If voltage is constant, power increases with increasing current.
