Electricity
| Question | Answer |
|---|---|
| an electric current is? | a flow of electrons |
| what electric current can be used in electrotherapy? | high frequency currents of high voltage |
| examples of solid conductors are | metals |
| liquid conductors are | fluids in which ions are present, body fluids and alkali |
| what gas can conduct electric current? | neon |
| examples of insulators are | plastics,rubber |
| the strength of an electric current is measured by | wattage |
| in an electrical circuit, if the voltage is doubled and the resistance halved, the intensity of the current is | is increased four times |
| the unit of current strength is | ampere |
| the unit of current pressure is | volt |
| the unit of electrical resistance is | ohm |
| the unit of electrical power is | watt |
| the current with a constant strength used in beauty therapy is called | galvanic |
| a so-called "faradic type current" is | an interpreted galvanic current |
| the current that is used to tone muscles is called | faradic |
| a so- called "faradic type current" is different from s galvanic current in beauty therapy because | it is more effective for training muscles |
| a galvanic current is different from a so-called "faradic type current" in beauty therapy because | it is more effective for iontophoresis |
| what machine for treatments in beauty therapy supplies galvanic current | a machine for iontophoresis |
| what beauty treatments in beauty therapy is galvanic current usedq | intophoresis |
| what treatments in beauty thrapy is galvanic current used | inotophoresis and electric desincrustation |
| the meaning of iontophoresis | to force cosmetic ingredients deeper into the skin |
| the meaning of desincrustation | to remove substances from the skins surface |
| desincrustation to remove substances from the surface of the skin is done with a | galvanic machine and cathode as the active electrode |
| the effect of desincrustation on sebum is | a saponification process caused by galvanic current |
| a machine for ionophoresis is most likely to contain | a rectifier and transformer |
| the electrical device that changes alternating current into direct current is a | rectifier |
| the function of a rectifier is to change | an alternating current into galvanic current |
| when do the electrodes in electrotherapy have to be moistened or to be applied on a moistened skin | in iontophoresis and not short wave diathermy |
| what can occur if a galvanic electrode is not applied to the skin with a regular pressure all over the surface of the electrode | on the spot of the highest pressure skin burning can occur |
| the electrical device that changes voltage is called a | transformer |
| the function of a transformer is to change | the voltage of an alternating current to a diffferent voltage |
| a fuse is an electrical apparatus | is the weakest part of the electrical circuit |
| a fuse is and electrical device that | protects apparatus or circuits from overloading |
| the saftey protection that should be observed in a beauty salon when using electrical appliances | are the responsibility of the employer of the salon |
