Peak current is increased by a factor of 2 then percentage change in <p> is

Correct answer: A. 100%

  • A. 100%
  • B. 200%
  • C. 50%
  • D. No change

Explanation

In alternating current (AC) circuits, when the peak current is doubled, this results in a 100% increase in the peak current. The percentage increase is calculated as follows: [(New Value - Original Value) / Original Value] x 100% = [(2I - I) / I] x 100% = [I / I] x 100% = 100%. Therefore, doubling the peak current results in a 100% increase. The other options are incorrect because they do not accurately reflect the percentage change resulting from doubling the peak value.

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.
