MSSC CPT Maintenance Awareness Exam with Frequently asked Questions and Verified Answers

MSSC CPT Maintenance Awareness Exam with Frequently asked Questions and Verified Answers A conductor has a resistance of 10 ohms and a current of 2 amperes flows through it. What is the voltage across the conductor? A) 5 volts B) 10 volts C) 20 volts D) 2 volts Correct Answer B) 20 volts Rationale Ohm’s Law states V = I × R. Therefore, V = 2 A × 10 Ω = 20 V. A series circuit contains three resistors: 5 Ω, 10 Ω, and 15 Ω. What is the total resistance? A) 30 Ω B) 25 Ω C) 20 Ω D) 15 Ω Correct Answer A) 30 Ω Rationale In a series circuit, resistances are added directly: 5 + 10 + 15 = 30 Ω. In a parallel circuit, what happens to total resistance when more branches are added? A) It increases B) It decreases C) It stays the same D) It becomes zero Correct Answer B) It decreases Rationale Adding more parallel branches provides additional paths for current, reducing overall resistance.
