Gunnebo Electrician Interview Questions and Answers

The capacitor unit is a measure of capacitance, which is the ability of a capacitor to store electrical energy.

• Capacitor unit is measured in farads (F).

• It represents the amount of charge a capacitor can store per unit voltage.

• Common capacitor units include microfarads (μF), nanofarads (nF), and picofarads (pF).

The resistance unit is the ohm (Ω), which measures the opposition to the flow of electric current.

• The resistance unit is named after the German physicist Georg Simon Ohm.

• It is represented by the symbol Ω.

• Resistance is measured using an ohmmeter.

• Common examples of resistance units include kilohm (kΩ) and megohm (MΩ).

The voltage unit is a measure of electrical potential difference.

• Voltage is measured in volts (V).

• It represents the amount of electrical potential energy per unit charge.

• Common examples of voltage units include millivolts (mV), kilovolts (kV), and megavolts (MV).

The current SI unit is the ampere (A).

• The SI unit for electric current is the ampere (A).

• The ampere is defined as the amount of electric charge that flows through a conductor in one second when a current of one ampere is applied.

• The symbol for ampere is A.

• The ampere is named after the French physicist André-Marie Ampère.

The SI unit for battery is the volt (V).

• The SI unit for battery is the volt (V).

• The volt is a measure of electric potential difference.

• It represents the amount of electrical energy per unit charge.

• For example, a typical AA battery has a voltage of 1.5 volts.
