If the peak value of current and voltage are doubled then percentage change in <p>?
Correct answer: A. 300%
- A. 300%
- B. 200%
- C. 100%
- D. none
Explanation
In an electrical circuit, the power (P) is given by the formula P = Vpeak * Ipeak, where Vpeak is the peak voltage and Ipeak is the peak current. If both the peak voltage and peak current are doubled, the new power becomes (2Vpeak)*(2Ipeak) = 4Vpeak*Ipeak. This results in a fourfold increase in power, which translates to a 300% increase (since the original power was 100%, and now it is 400%). Therefore, the correct answer is Option A, which reflects a 300% increase in power. Other options do not correctly capture this exponential power increase.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
