A single$-$phase transformer draws a no$-$load current of $12\mathrm{.}5$ A at a power factor of $0,4$ lagging from a $1500$ V supply. When a load is connected across the $F_2$ secondary winding, the current drawn from the supply increases to $\frac{175}{b}ar(A)$ at a power factor of $0,82$ lagging. Calculate the current delivered to the load and the power factor. Take the secondary voltage to be $300$ V and ignore all voltage drops.
