What is potential difference when 0.5 amp current flows through a conductor having resistance `12 Omega`?

When a resistance of 12 Omega is conencted with a cell of emf 1.5 V,0.1 A current flows through the resistance internal resistance of the cell is

Calculate the current flow through a conductor having 60Omega resistance and potential’ difference is 36V.

When a resistance of 12 Omega is connected with a cell of emf 1.5 V, 0.1A current flows through the resistance. Internal resistance of the cell is—

Two resistances r_1 and r_2 , when connected separately to the same potential difference, it was seen that the current flowing thought r_1 was six times the current flowing through r_2 . Determine the ratio of r_1 and r_2 .

How much quantity of heat will be evolved when 10 amp electric current is passed through a 30Omega resistance for 5 minutes?

Emf, of a cell is 1.5 V and its internal resistance is 1 Omega When the cell sends current in an external circuit having resistance 2 Omega , then what will be the value of lost volt?

When 100 volt dc is applied across a conducting coil, a current of 1A flows through it. When 100 volt ac of 50 cycles per second is applied to the same coil, only 0.5 A current flows through it. Calculate resistance of coil

Resistance of a conductor is twice that of another conductor and the potential differences between the two ends of the two conductors are same. Find the ratio of strengths of currents flowing, through them.
