electricity terminology

QuestionAnswer
Accommodation: Accommodation is an occurrence whereby a nerve and muscle membraneʼs threshold for excitability increases secondary to a stimulation by a pulse that has a slow phase rise time. The quicker the rise time, the less the nerve can accommodate to the impulse.
Alternating current (biphasic): allows for the constant change in flow of ions.
Ampere: is a unit of measure used to describe the rate of current.
Amplitude: refers to the magnitude of current. Amplitude controls are often labeled intensity or voltage.
Anode: used during direct current electrotherapy is the positively charged electrode that attracts negative ions.
Biphasic: describes a pulse that moves in one direction, returns to baseline, then in the other direction and back to baseline again within a predetermined amount of time.
Burst: is an interrupted group of pulses that are delivered in a finite series and a predetermined frequency.
Cathode: used during direct current electrotherapy is the negatively charged electrode that attracts positive ions.
Conductance: describes the ease at which a particular material will allow current flow.
Current: describes the flow of electrons from one place to another.
Direct current (monophasic or Galvanic):Direct current refers to the constant unidirectional flow of ions. The direction of the current is dependent on polarity.
Duty cycle: refers to the percentage of time that electrical current is on in relation to the entire treatment time.
Electrical impedance: is the resistance of a tissue to electrical current.
Frequency: determines the number of pulses delivered through each channel per second. Frequency controls are often labeled rate.
High-volt current: is characterized by a waveform greater than 150 volts with a short pulse duration. High-volt is intermittent and is used for deeper tissue penetration.
Impedance: is the property of a substance that provides resistance to the flow of current by offering an alternate current.
Interpulse interval: is the period of time of electrical inactivity between each pulse, usually expressed in microseconds or milliseconds.
Ion: is a positively or negatively charged atom.
Low-volt current: is characterized by a waveform of less than 150 volts and is used for neuromuscular stimulation.
Monophasic: describes a pulse that has either a positive or negative polarity and moves in only one direction from a zero baseline and returns to the baseline within a predetermined amount of time.
Ohmʼs law: . describes the current of an electrical circuit. There is a direct proportional relationship between current and voltage and an indirect proportional relationship between current and resistance
Pulse: is one individual waveform.
Pulse duration: is the amount of time that it takes to complete all phases of a single pulse (which is also termed the positive phase of the waveform). Pulse duration controls are often labeled pulse width.
Pulsed current (interrupted): allows for a non-continuous flow of either alternating or direct current with periods of no electrical activity.
Ramp: refers to the number of seconds it takes for the amplitude to gradually increase or decrease to the maximum value set by the amplitude control.
Volt: is a unit of measure of electrical power or electromotive force.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
