155055 A Primary coil is connected with an AC source and a bulb is connected with the secondary coil. The voltage across the bulb is $6.0 \mathrm{~V}$ and the current through the bulb is $0.4 \mathrm{~A}$. The turns ratio is $5: 1\left(N_{p}: N_{s}=5: 1\right)$. Calculate the current in the primary coil.
