As you need the Railway Recruitment Board Ajmer Jr. Engineer Previous year question paper, here I am uploading a document file which contains the same, you can use this question paper in your studies, there are objective types of the questions available. Following are the questions of the attachment: 1. A resistance of 10 ohm is connected across a supply of 200V. If resistance R is now connected in parallel with a 10 ohm resistance, the current drawn from the supply gets doubled. The value of unknown resistance R is (a) 5 ohm (b) 20 ohm (c) 10 ohm (d) 15 ohm Ans : c 2. Kirchhoff’s first law is also called as (a) voltage law (b) Current law (c) Mesh Current law (d) All the above Ans : b 3. Find the total resistance when four 3 Ohm resistance are connected in series (a) 3 ohm (b) 12 ohm (c) 14 ohm (d) 8 ohm Ans : b 4. The practical unit of power is (a) Joule (b) Ampere (c) Watt (d) Weber Ans : c 5. Form factor of a sine wave is (a) 1.414 (b) 1 (c) 0 (d) 1.11 Ans : d 6. The unit of resistance is (a) Mho (b) ohmm (c) Ohms (d) Amps Ans :c 7. Unit of impedance is (a) Ampere (b) Volt (c) Ohm (d) mho Ans : c Complete question paper is in the attachment, please click on it…….. Last edited by Sashwat; July 1st, 2019 at 12:45 PM.
