Answer:
Technician B
Explanation:
Resistance,
where V is the voltage and I is the current in amps
Therefore, 
Power=VI=12*12=144 W
Therefore, the power is 144 W and resistance is 1 Ohm. This implies that technician A is wrong while technician B is correct
Answer:
Recessed safe
Explanation:
A recessed, receptacle or plug is one in which the metal interfacing parts have been retracted back in such a way that common contact between a person handling the receptacle or outlet will not ordinarily lead to exposure to electric shock hazard and as such improving the safety of use of such plug, receptacle or electrical device either at home or in industrial setting
A recessed outlet is also more ideal than standard outlets where there are hazards such as potential contact with water.
