Answer:

Technician B

Step-by-step explanation:

Resistance,
$R=\frac {V}{I}$ where V is the voltage and I is the current in amps

Therefore,
$R=\frac {12}{12}=1 ohm$

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
