Differentiate between primary and secondary cells.

The primary of a transformer when connected to a dc battery of 10 volt draws a current of 1 mA. The number of turns of the primary and secondary windings are 50 and 100 respectively.The voltage in the secondary and the current drawn by the circuit in the secondary are respectively

What advantage do the fuel cells have over primary and secondary batteries?

Why are wind currents generated?

If a transformer have turn tatio 5, frequency 50 Hz root mean square value of potential difference on primary 100 volts and the resistance of the secondary winding is 500 Omega then the peak value of voltage in secondary winding will be (the efficiency of the transformer is hundred percent)
