In a step up transformer, primary power is 50 W and output voltage is 100V. If the current in the primary is 1 A.
What is the primary voltage ?

There are 10000 turns in the primary and 500 turns in the secondary of a transformer.The primary voltage is 240 V and intensity of current in the primary is 0.1 A.Find the intensity of current if the secondary voltage is 12V ?

A transformer without power loss carries 4000 turns in the primary and 2000 turns in thw secondary. If the primary voltage is 120 V and the current is 0.2 A . What is the output voltage of transformer ?

In a transformer without any loss in power , there are 5000 turns in the primary and 250 turns in the secondary. The primary voltage is 120 V and the primary current is 0.1 A. Find the voltage and current in the secondary.

The input voltage of a transformer is 240 V AC . There are 80 turns in the secondary coil and 800 turns in the primary. What is the output voltage of the transformer ?

In a trasnsformer, if the voltage of the primary is V_p and the current in the primary id I_p voltage in the secondary is Vs and the current Is ,write down the formulae conecting them.
