1

The flow of electric current is measured in what unit?

Amps

2

What is the term used to denote the total opposition to flow of alternating current in a circuit?

Impedance or resistance (ohms)

3

What is the most common DC electric power source?

Batteries. Defibrillators use batteries to charge a capacitor.

Filters

Capacitors

7

What is the unit for energy?

Joule (J)

8

How are EP lab defibrillators tested?

Discharging paddles into a dummy load
