Electrical RECF Questions and Answers 100% Pass In a series circuit voltage is additive In a series circuit current is constant In a series circuit resistance is additive In a parallel circuit voltage is constant In a parallel circuit current is additive In a parallel circuit resistance is 1/1/R+Rn A.M. means amplitude modulation F.M. means frequency modulation Amplitude measures how high something is Frequency measures how much something happens in a given period of time An electromagnetic motor has electricity flowing through thousands of wire coops called ______ Windings EMF means Electro Magnetic lines of Flux What is the job of thousands of wire coops? Pick up EMF which touches other loops and creates electricity Why does electricity have polarity? They emit EMF Electricity moves through wires in a similar motion to what magnets. (opposites attract) How is motion produced by Changing polarity what is the shortcut when finding the total resistance in a parallel circuit when all the resistors are the SAME value. Value of 1 resistor / Number of resistors. A 20 ohm resistor, a 10 ohm resistor, and a 20 ohm resistor are all connected in parallel. What is the total resistance? 5 ohms A 20 ohm resistor, a 10 ohm resistor, and a 20 ohm resistor are all connected in parallel. In series with the second 20 ohm resistor is a 15 ohm resistor. Now, what is the total resistance? 20 ohms memory device called ROM (read only memory) can be programmed only once, if you are keeping a lifetime database about a specific person. What type of information would make sense to store in ROM? Date of Birth 2 Computer memory types RAM and ROM What is RAM Random Access Memory
