what is meant by wattless current?

Expert Answer:
Dear student
The current which does not dissipates any energy is called wattless current. In an AC circuit, the capacitor and inductor oppose the change in current , but do not dissipate it. Instead, they store the energy in form of electric and magnetic field respectively. At the time of resonance, the potential difference across capacitor-inductor is zero. The current flowing at this time is called wattless current. For the same reason, capacitor and inductor are also called wattless components.
Hope this helps.
