Answer :
Given, Current, I = 0.5 A Resistance, R = 6 WUsing Ohm's law we know that V = IRSo, V = 0.5 × 6 = 3 VThus, the main answer is: The emf of the ideal battery is 3V.
As we know that Ohm's law is the mathematical expression of the relationship between voltage, current and resistance in a circuit. It says that the current through a conductor between two points is directly proportional to the voltage across the two points.Here, we are given the current passing through a resistor and the resistance of that resistor.
We can use Ohm's law to calculate the voltage drop across that resistor. Therefore, V = IR. Substituting the given values, we get V = 0.5 × 6 = 3 V.So, the emf of the ideal battery is 3V.
