(b) A medical technology company is designing a new portable defibrillator for reviving patients whose heart has stopped. The capacitor in the device will be charged to 2000 V and is required to deliver 400 J of energy on discharge. i) Calculate the capacitance required for this capacitor ii) The conducting plates of the capacitor must have an area of 5 m² and be separated by an insulator with thickness of 0.05 mm. Determine the value of dielectric constant for the insulator between the capacitor parallel plates to deliver the intended energy to the patient
