Answer:
A real emf device has internal resistance and an ideal emf device does not.
Answer:
A real emf device has internal resistance and an ideal emf device does not
Explanation:
What is EMF?
The electromotive force or potential difference or voltage is the reason behind the flow of current in a circuit.
What is Ideal emf device?
The ideal emf device is one which doesn't have any internal resistance and it provides a fixed emf regardless of the load current.
What is Real emf device?
But nothing is ideal in real world, A real emf device would have some internal resistance in series with the emf device.
Conclusion:
The internal resistance causes voltage drop therefore, as the load current changes, the voltage drop changes and hence device emf changes.
