Electronic Engineering Test Questions With Correct Answers
ELECTRONIC ENGINEERING TEST QUESTIONS WITH CORRECT ANSWERS State Ohm's law - ANSWER V=IXR R=V/I I=V/R If current goes down, what does resistance do? - ANSWER Reistance goes up If Voltage is CONSTANT and Resistance goes DOWN, what must Current do? - ANSWER Current HAS to go UP! What is the definition of a short circuit? - ANSWER Zero resistance. Circuit has high current, and zero resistance. What would cause Current to DECREASE in a circuit, IF Voltage remained CONSTANT? - ANSWER INCREASSE in Resistance What is a Transformer? - ANSWER An electrical device that transfers energy from one electrical circuit to another by magnetic coupling, aka: Mutal Induction. One set of windings induce a voltage in the other set of windings. What are Transformers used for? - ANSWER Used to convert between high and low voltages and for impedance transformation. State the Power formula. - ANSWER P = V X I power equals voltage times current
