What is the purpose of a transformer? - to change voltage and current level transformers do not generate power..... - they transfer power what is the schematic symbol for a transformer? - what is the the input of a transformer called? - the primary (typically on the left due to the power supply) what is the output of a transformer called? - the secondary What is the designation symbol for a transformer? - T What is mutual inductance? - The ability of the magnetic field of one coil to induce voltage in a second coil What is EP? - Primary Voltage what is Es? - Secondary Voltage What is NP? - Number of turns in primary What is NS? - Number of turns in secondary NP=NS - Not electrically connected NP>NS - Steps down the voltage. NS is lower than NP, ES is lower than EP. NP<NS - Steps up the voltage. NS is greater than NP, ES is greater than EP. What is phase inversion? - can reverse the phase of the applied AC voltage or sine wave Primary coil receives ___________ voltage - Input Secondary coil receives _______ voltage - induced Step up transformers __________ the applied voltage - increase Step down transformers ____________ the applied voltage - decreases What are the three important circuit values of a transformer? - turns ratio, voltage, current what is turns ratio? - it compares the number of turns in the primary to the number of turns in the secondary What is the turns ratio formula? - Diode= One Direction -
