To determine the effective or RMS (Root Mean Square) current value for an AC current with an amplitude of 10 A, you need to use the relationship between the peak current and the RMS current for a sinusoidal waveform.
For a sinusoidal waveform, the RMS current (Iᵣₘₛ) can be calculated as:
Iᵣₘₛ = Iₚₑₐₖ / √2
where Iₚₑₐₖ is the peak current.
Given that the amplitude of the AC current is 10 A, we can consider this value as the peak current.
Substituting the value into the formula:
Iᵣₘₛ = 10 A / √2 ≈ 7.07 A
Therefore, the effective (RMS) current value for an AC current with an amplitude of 10 A is approximately 7.07 A.
