Electrical Engineering : What is the unit of electric current?
  • Volt
  • Watt
  • Ampere
  • Ohm
Explanation: The SI unit of electric current is Ampere.
Which device converts AC to DC ?
  • Transformer
  • Inverter
  • Rectifier
  • Generator
Explanation: A rectifier converts Alternating Current (AC) to Direct Current (DC).
In a parallel circuit, the voltage across each component is:
  • Different
  • Zero
  • Same
  • Half
Explanation: In a parallel circuit, the voltage is the same across all components.
Ohm’s Law is given by:
  • V = IR
  • V = I + R
  • I = V + R
  • R = V × I
Explanation: Ohm’s Law shows the relationship between voltage, current, and resistance. Formula: V = I × R Where: • V = Voltage (in volts) • I = Current (in amperes) • R = Resistance (in ohms)
Electrical Engineering : What is the unit of resistance?
  • Ampere
  • Volt
  • Watt
  • Ohm
Explanation: The SI unit of electrical resistance is the Ohm (Ω). It measures how much a material resists the flow of electric current.
Electronics & Instrumentation : A capacitor stores energy in:
  • Magnetic field
  • Electric field
  • Thermal energy
  • Mechanical energy
Explanation: A capacitor stores energy in the electric field created between its two plates when charged.
The function of a thermocouple is to:
  • Measure pressure
    • Explanation: A thermocouple generates a voltage based on the temperature difference between two junctions, which is used to measure temperature.
