Tutorial on L1 to L3 of Current Electricity

A transformer has 250 primary turns and 500 secondary turns. If 200 V electric potential is applied to the primary resulting in a current of 5 mA, find the secondary voltage and current.

The potential difference between the terminals of an electric heater is 60 V when it draws a current of 4 A from the 3 source. What current will the heater draw if the potential difference is increased to 172.5 V?

When a resistor of 11 Omega is connected in series with an electric cell, the current following in it is 0.5 A . Instead, when a resistor of 5 Omega is connected to the same electric cell in series, the current increases by 0.4 A The internal resistance of the cell is
