In the given case, photoelectric current surely increases.
If the wavelength of an electromagnetic radiation is doubled, it would only increase the number of photoelectrons, but there would be no energy change. If a frequency of incident radiation is fixed, the photoelectric current would increase linearly with increase in intensity of incident radiation.
