Answer:
A. simple to construct and easy to repair
Explanation:
A dynamic microphone works on the principle of electromagnetic principle. A diaphragm is attached to a coil of wire which helps in producing sound. Responding to the sound waves, the coil of the wire is vibrated by the diaphragm. A magnetic field is created by the magnet which is present inside the coil of wire. The electrical signal is generated in response to the motion of the coil. The speed of the motion produces the amount of the current.
Since the construction of a dynamic microphone is easier as compared to any other microphone, John is likely to opt to build one.
1. The current is the same everywhere in the circuit. This means that wherever I try to measure
the current, I will obtain the same reading.
2. Each component has an individual Ohm's law Voltage Drop. This means that I can calculate
the voltage using Ohm's Law if I know the current through the component and the resistance.
3. Kirchoff's Voltage Law Applies. This means that the sum of all the voltage sources is equal to
the sum of all the voltage drops or
VS = V1 + V2 + V3 + . . . + VN
4. The total resistance in the circuit is equal to the sum of the individual resistances.
RT = R1 + R2 + R3 + . . . + RN
5. The sum of the power supplied by the source is equal to the sum of the power dissipated in
the components.

I think it’s D. Sorry if it’s wrong
