356291 A transformer with efficiency 80% works at 4 \(kW\) and 100 \(V\). If the secondary voltage is 200 \(V\) then the primary and secondary currents are respectively:

356292 A power transmission line feeds input power at \(2300\;V\) to a step down transformer with its primary windings having 4000 turns giving the output power at \(230\;V\). If the current in the primary of the transformer is \(5\;A\) and its efficiency is \(90 \%\) the output current would be:

356293 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 \(\phi = {\phi _0} + 4t\), where \(\phi \) is in weber, \(t\) is time in second and \(\phi \) is a constant, then the output voltage across the secondary coil is

356294 The turns ratio of a transformer is given as 8 : 3. If the current through the primary coil is 3 \(A\), then calculate the current through load resistance.
