Short-circuit test on a single-phase transformer at 1 kHz gives: wattmeter \(P=8\) W, primary current \(I=2\) A, primary voltage \(V=6\) V. Assume negligible no-load loss/current and linear core. With the secondary shorted, the primary is now fed from a \(2\) V\(_{\mathrm{RMS}}\), 1 kHz source in series with a capacitor of value \( \dfrac{1}{2\pi\sqrt{5}} \) mF. The primary RMS current is _____A (rounded off to two decimals).
