The output voltage of a transfor mer connected to $220 V$ line is $1100 V$ at 2 Acurrent. Itsefficiency is $100%$ . The current coming from the line is

Options:

Answer:

Solution:

For $100%$ efficiency For $100%$ enciency- $V_{s} i_{s} = V_{p} i_{p}$ $1100 \times 2 = 220 \times i_{p}$ i.e., Primary current, $i_{p} = 10 A$ PART - II (CHEMISTRY)
