PHXII07:ALTERNATING CURRENT

356325 The turns ratio of a transformer is given as 2 : 3. If the current through the primary coil is 3 \(A\), thus calculate the current through load resistance.

1 \(1\,A\)
2 \(4.5\,A\)
3 \(2\,A\)
4 \(1.5\,A\)
PHXII07:ALTERNATING CURRENT

356326 The ratio of secondary to the primary turns in a transformer is \(3: 2\). If the power output be \(P\), then the input power neglecting all losses must be equal to:

1 \({5{\rm{ }}P}\)
2 \(1.5\,P\)
3 \(P\)
4 \({2{\rm{/}}5{\rm{ }}P}\)
PHXII07:ALTERNATING CURRENT

356327 The magnitude of the \(e\).\(m\).\(f\). across the secondary coil of a transformer does not depend on

1 The number of the turns in the primary
2 The number of the turns in the secondary
3 The magnitude of the e.m.f applied across the primary
4 The resistance of the primary and the secondary
PHXII07:ALTERNATING CURRENT

356328 The turns ratio of a transformer is \(3: 2\). If the current through the primary coil is \(3\;A\), then the current through load resistance is

1 \(1\;A\)
2 \(4.5\;A\)
3 \(2\;A\)
4 \(1.5\;A\)
