# 003,004,005 Unit of measurement, related terms, and effects of current flow,voltage, resistance

 what unit of measure is current flow measured in? Ampere (amps) what is the symbol for Current? (used in math formulas) I (intensity) what is the for current used om drawings? A (ampere) what tool is used to measure current flow? ammeter direction of current flow in conventional current flow which way does current flow? positive to negative Effects of Current Flow what are the 4 effects of electron flow? heatchemical changemagnetismphysical shock Voltage Defined what is electromotive force(EMF)? the force to move electrons from one atom to another Voltage Defined what are the other names for voltage electrical pressuredifference of potentialElectromotive force(EMF) Voltage Defined what is the basic unit of measure for electron moving force? volt Voltage Defined what is the symbol for voltage when used in math? E Voltage Defined what is the symbol for voltage when used in drawings V Voltage Defined what tool is used to measure volts voltmeter Resistance Defined what is the opposition to current flow? resistance Resistance Defined what is resistance measured in? ohms Resistance Defined what is the math symbol for resistance? R Resistance Defined what is the symbol for resistance in drawings? Ω Factors that affect resistance what are the 4 factors that affect resistance length of conductorssize of conductorconductor materialtemperature Length of Conductors T/F longer conductors have more resistance True size of conductors larger wires have more or less resistance? lessbec there is more surface area for current to pass type of material T/F the type of material used as a conductor has no effect on the amount of current that can flow thru it Falsesome materials are insulators and some are conductors Temperature what happens to the resistance as the temperature increases? the resistance increases Authordaniel.ramos702 ID351997 Card Set003,004,005 Unit of measurement, related terms, and effects of current flow,voltage, resistance Description003 Unit of measurement, related terms, and effects of current flow Updated2020-05-14T21:23:16Z Show Answers
