155464 The primary and secondary coils of a transformer have 50 and 1500 turns respectively. If the magnetic flux $\phi$ linked with the primary coil is given by $\phi=\phi_{0}+4 \mathrm{t}$, where $\phi$ is in weber, $t$ is time in second and $\phi_{0}$ is a constant, the output voltage across the secondary coil is

155367 A $12 \mathrm{~V}, 60 \mathrm{~W}$ lamp is connected to the secondary of a step down transformer, whose primary is connected to ac mains of $220 \mathrm{~V}$. Assuming the transformer to be ideal, what is the current in the primary winding?
