Fundamentals of Electrosurgery Flashcards
1
Q
Impedance refers to opposition/resistance of flow of electrons to AC current. True / False?
A
True
2
Q
Resistance refers to opposition/resistance of flow of electrons to DC current. True / False?
A
True
3
Q
The greater the distance between electrodes, the greater the impedance. True / False?
A
True
4
Q
Power is measured in…
A
Watts
5
Q
Define power:
A
Power is the amount of heat energy produced by resistance. Measured in Watts. Watts is calculated by multiplying the current by voltage
6
Q
Define voltage:
A
Voltage is the FORCE responsible for moving electrical current (electrons) a through resistance within a circuit.
7
Q
Define current:
A
Current is the rate of the flow of electrons
8
Q
Current is measured in…
A
Amperes (amps)
9
Q
A
