10+ Biomedical Engineer Interview Questions and Answers for Freshers

The charging and discharging time of a perfect defibrillator is almost instantaneous.

• A perfect defibrillator has no charging or discharging time as it can deliver an electric shock instantly.

• This is because a perfect defibrillator does not require any time to charge up its capacitors before delivering the shock.

• Similarly, there is no time delay in discharging the stored energy to the patient's body.

• In reality, defibrillators have some charging and discharging time due to the ...read more
