Answer:
A. energy source
Explanation:
An energy source like a batter or emf can move electrons through the circuit of what it's connected to and provide a force field (the case of the battery)
For an ideal transformer power loss is assumed to be zero
i.e. the power in primary coil due to input voltage must be equal to power in secondary coil due to output voltage
this can be written in form of equation
here we know that
So primary coil voltage is 49 Volts
