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.

4

Electric battery current has a frequency of what?

0 Hz.
DC current flows steadily from - to +. it does not alternate like AC does.

5

The elimination of vibrations at certain frequencies is accomplished through the use of what electronic devices?

Filters

6

When a DC defibrillator "charges" it stores electrical energy in what?

Capacitors

7

What is the unit for energy?

Joule (J)

8

How are EP lab defibrillators tested?

Discharging paddles into a dummy load

9

What is the current drawn by a resistor of 100 ohms, if a 10 volt battery is applied across it?

0.1 amp
I=V/R
