Span Pumps Interview Questions, Process, and Tips

Yes, solar panels are devices that convert sunlight into electricity.

• Solar panels are made up of photovoltaic cells that absorb sunlight and convert it into direct current (DC) electricity.

• This DC electricity is then converted into alternating current (AC) electricity through an inverter, which can be used to power homes and businesses.

• Solar panels are becoming increasingly popular as a renewable energy source due to t...read more

Diodes allow current to flow in one direction while batteries convert chemical energy into electrical energy.

• Diodes are semiconductor devices that have a p-n junction and allow current to flow in one direction only.

• Batteries convert chemical energy into electrical energy through a chemical reaction.

• The voltage of a battery is determined by the materials used in the electrodes and the electrolyte.

• Different types of batt...read more

AC motor works on the principle of electromagnetic induction to convert electrical energy into mechanical energy.

• AC current is supplied to the stator winding, which creates a rotating magnetic field.

• This rotating magnetic field induces a current in the rotor winding, which creates a magnetic field that interacts with the stator field.

• The interaction between the two fields causes the rotor to rotate, converting electric...read more

In house wiring, we use alternating current (AC) power.

• AC power is used in most homes and buildings for lighting, appliances, and other electrical needs.

• The voltage used in house wiring is typically 120 or 240 volts, depending on the country and region.

• Wiring is typically done with copper or aluminum conductors, and is protected by circuit breakers or fuses.

• Grounding is an important safety feature in house wiring, prov...read more
