Answer 8

stable subatomic particle with a negative electirc charge

and eel is subatomic

Question 9

Current

Answer 9

net movement of electrons along a conducting medium in response to an applied electrical field. The rate at which electrons flow past a point in a complete electrical circuit. (flow of charged particles)

current = flow

Question 10

Ampere

Answer 10

unit of measurement indicating rate of which electrical current is flowing

A - a in rate

Question 11

Voltage

Answer 11

force resulting from an accumulation of electrons at one point. The “pressure” that pushes electricity

Question 12

Conductance

Answer 12

the ease at which a current flows along a conductive medium

C= current and conductive

Question 13

Ohm

Answer 13

measurement of resistance
Voltage = current x resistance

“OHM” = resistance voltage

Question 14

Insulator

Answer 14

materials that resist current flow

Insulator - keeping things out (resisting)

Question 15

Resistance

Answer 15

goes against (opposition) the conductive flow or current

Question 16

Current flow

Answer 16

voltage/resistance, flow of charged particles

Answer 21

continuous, bidirectional flow of charged particles.
Flowing back and forth.
(TENS, NMES, IFC, russion)

Question 22

Pulsed current

Answer 22

interrupted flow of charged particles where the current flows in a series of pulses separated by periods where no current flow.
