Technician a Says That the Actuation Voltage Used to Drive

Multiple Choice

Technician A says that the actuation voltage used to drive CR electrohydraulic injectors (EHIs) is typically around 100 volts when they use solenoid actuators. Technician B says that EHI piezo actuator resistance reading tend to be higher solenoid-actuated EHIs, for EHIs that use piezo actuators is usually much higher than 100 volts. Who is correct?

A) Technician A only
B) Technician B only
C) Both A and B
D) Neither A nor B.
