Ohm's Law relates V, I, and R as V = I×R. 12 Which component stores electrical energy in a magnetic field? a Resistor b Capacitor c feedback_1_0_words_title_fix_incorrect_A:An inductor uses magnetic fields for energy storage. d Inductor e Diode 13 What does a diode primarily do in a circuit? a Stores charge b Amplifies AC signals c Increases resistance d Allows current in one direction e feedback_2_0_words_title_fix_incorrect_A:Diodes are unilateral conductors. 14 Which quantity is measured in volts? a feedback_3_0_words_title_fix_incorrect_A:Voltage measures potential difference between two points. b Electric potential difference c Charge d Inductance e Capacitance 15 What is the unit of resistance? a feedback_4_0_words_title_fix_incorrect_A:Resistance uses the symbol Ω, named ohms. b Siemens c Tesla d Ohm e Henry 16 Which circuit element obeys Ohm’s law linear with voltage and current? a Inductor b Transformer c feedback_5_0_words_title_fix_incorrect_A: Ohmic resistors have a linear V-I relationship. d Resistor (ohmic) e Capacitor 17 What does a capacitor primarily store? a Electrical energy in an electric field b feedback_6_0_words_title_fix_incorrect_A: Capacitors store energy in the electric field between plates. c Kinetic energy d Magnetic energy e Chemical energy 18 Which parameter indicates a transistor’s current amplification? a feedback_7_0_words_title_fix_incorrect_A: Beta is the DC current gain abbreviation for BJT. b Resistance c Inductance d Current gain (beta) e Capacitance 19 What is AC signal's frequency unit? a Volt b Hertz c feedback_8_0_words_title_fix_incorrect_A: Frequency is measured in Hz. d Watt e Ampere 20 In a simple series circuit, how are voltage drops distributed? a Only the largest drop matters b They sum to the supply voltage c feedback_9_0_words_title_fix_incorrect_A: Kirchhoff's voltage law states the sum equals supply. d Drops cancel out e Each drop is equal 21 What is the primary purpose of a P-trap in a sink or toilet? a To filter impurities from water b To increase water pressure c To slow down the water flow to reduce noise d To prevent sewer gases from entering the building 22 Which tool is commonly used to tighten or loosen plumbing fittings without damaging them? a pliers (non-adjustable) b hammer c adjustable wrench d saw 23 Which material is commonly used for residential supply lines in newer homes for copper tubing? a PEX-A b Cast iron c Type L copper d PVC 24 What does a Oatey or Teflon tape primarily prevent? a Rust formation b Corrosion of metal pipes c Leaks at threaded connections d Water hardness 25 Which device detects leaks and alerts a homeowner in a water-supply line? a Flow sensor or water-leak detector b Air admittance valve c Pressure relief valve d Backflow preventer 26 Which term describes blocking sewer gas and pests from entering while allowing wastewater to drain? a Trap b Cleanout c Vent d Valve 27 What is the main function of a vent pipe in a plumbing system? a To filter contaminants b To bring fresh air into rooms c To equalize pressure and allow drainage d To heat water 28 Which pipe material is commonly used for drain-waste-vent (DWV) systems in many buildings? a Copper b PVC c CSST d PEX 29 What does a pressure-reducing valve (PRV) do in a home plumbing system? a Reduces incoming water pressure to a safe level b Increases water flow c Raises boiler temperature d Filters sediments 30 Which action best prevents frozen pipes in winter? a Paint pipes black to absorb heat b Insulate exposed pipes and maintain warm indoor temps c Install larger pipes d Use more hot water taps Feedback 1 Risk assessments identify hazards, estimate risks, and implement controls to protect workers. 2 Eye protection prevents chemical splashes from injuring eyes. 3 Using legs and keeping a straight back reduces back injuries. 4 In many regions, OSHA (or equivalent) provides safety regulations. 5 Lockout/tagout ensures machines stay off during service. 6 Mandatory PPE signs remind workers to wear required protection. 7 Near-misses should be reported to prevent future harm. 8 Repetitive typing can cause musculoskeletal disorders. 9 SDS gives chemical hazards, handling, and first-aid info. 10 Ongoing training reinforces safe behaviors and readiness. 11 The correct relation is V = I × R. Other options mix symbols or refer to power. 12 Inductors store energy in a magnetic field; capacitors store energy in an electric field. 13 Diodes conduct in one direction and block the opposite direction. 14 Voltage equals the electric potential difference (potential energy per unit charge). 15 Resistance is measured in ohms. 16 Ohmic resistors follow V = I×R; non-ohmic like diodes do not. 17 Capacitors store energy electrostatically. 18 Beta (β) is the current gain of a bipolar junction transistor. 19 Frequency in AC circuits is measured in hertz (cycles per second). 20 Kirchhoff's voltage law: the algebraic sum of all voltages around a loop is zero, so drops sum to supply voltage. 21 P-traps seal with water to block gases; other functions are not the trap's main purpose. 22 An adjustable wrench provides a snug, adjustable grip; other tools can damage fittings. 23 Type L copper is a common, durable choice; PVC is for drains, PEX is another tubing type, CI is old. 24 PTFE tape seals threads to prevent leaks; it doesn’t prevent rust or hardness. 25 Water-leak detectors sense moisture; other devices have different roles. 26 A trap creates a water seal; vents, valves and cleanouts have other roles. 27 Vent pipes prevent pressure vacuum/air-lock; other options are unrelated. 28 PVC is standard for DWV; PEX for supply, copper for some old DWV, CSST for gas. 29 PRV lowers pressure to protect fixtures; other options describe different devices. 30 Insulation and temperature control prevent freezing; others are ineffective.
