Candidate check out these interesting and interactive Electrical Engineering questions on this page. Candidates need to do Practice to these questions and answers, which give them a very quick revision of most of the topics by which they become proficient in this disciplines.

Electrical Engineering Objective Type Questions

Q1- Which of the following is not an electrical quantity?





Q2- You are measuring the current in a circuit that is operated on an 18 V battery. The ammeter reads 40 mA. Later you notice the current has dropped to 20 mA. How much has the voltage changed?





Q3- The voltages in Problem 5 are measured at a certain frequency. To make the resistor voltage less than the inductor voltage, the frequency is





Q4- When the resistor voltage in a series RL circuit becomes less than the inductor voltage, the phase angle





Q5- A two-terminal variable resistor is known as a





Q6- A material that does not allow current under normal conditions is a(n)





Q7- How many watt-hours represent 65 W used for 18 h?





Q8- When the speed at which a conductor is moved through a magnetic field is increased, the induced voltage





Q9- For a given wirewound core, an increase in current through the coil





Q10- A capacitor and a resistor are connected in series to a sine wave generator. The frequency is set so that the capacitive reactance is equal to the resistance and, thus, an equal amount of voltage appears across each component. If the frequency is increased





Q11- If the frequency is halved and the resistance is doubled, the impedance of a series RL circuit





Q12- If the resistance in parallel with a parallel resonant circuit is reduced, the bandwidth





Q13- A 24 resistor, an inductor with a reactance of 120, and a capacitor with a reactance of 120 are in series across a 60 V source. The circuit is at resonance. The voltage across the inductor is





Q14- A 2 mH, a 3.3 mH, and a 0.2 mH inductor are connected in series. The total inductance is





Q15- How many degrees are there in /3 rad?





Q16-   In a three-phase system, when the loads are perfectly balanced, the neutral current is





Q17- The output of an RC integrator is taken across the





Q18- In a certain loaded transformer, the secondary voltage is one-fourth the primary voltage. The secondary current is





Q19- The primary winding of a power transformer should always be





Q20- When the pointer of an analog ohmmeter reads close to zero, the resistor being measured is
