USHA International Interview Questions, Process, and Tips

The difference between 40w and 100w bulb is the amount of power they consume. Wattage is used to measure it.

• Wattage is the amount of power consumed by a bulb.

• Higher wattage bulbs consume more power and produce more light.

• Lower wattage bulbs consume less power and produce less light.

• Wattage is measured in watts (W).

CFLs are more energy-efficient than bulbs but have a lower rating due to their initial cost and mercury content.

• CFLs use 75% less energy than bulbs and last up to 10 times longer.

• CFLs are more expensive to purchase initially but save money in the long run.

• CFLs contain small amounts of mercury, which can be harmful if not disposed of properly.

• Bulbs are cheaper and easier to dispose of but use more energy and have a shor...read more

Trains use both DC and AC voltage depending on the type of train and its power source.

• DC voltage is commonly used for electric trains powered by overhead lines or third rails

• AC voltage is used for trains powered by on-board diesel generators or locomotives

• The voltage used can vary depending on the country and the specific train system

• In the US, DC voltage for trains is typically around 600-750 volts, while AC voltage c

Laptop adapters and cell chargers have different voltage ratings.

• Laptop adapters usually have a voltage rating of 19V or 20V.

• Cell phone chargers typically have a voltage rating of 5V.

• It's important to use the correct voltage adapter for your device to avoid damage.

• Some adapters have adjustable voltage settings to accommodate different devices.

Solar cells convert sunlight into electricity. Energy can be stored in batteries. Cost varies depending on technology and scale.

• Solar cells use photovoltaic technology to convert sunlight into electricity

• The electricity can be stored in batteries for later use

• The cost of solar cells varies depending on the technology and scale of the installation

• Solar energy is becoming increasingly cost-competitive with traditional so...read more

The lux in the room varies depending on the light source.

• The lux level in the room can be measured using a lux meter.

• Halogens emit around 200-300 lux, while sunlight can emit up to 100,000 lux.

• The lux level in a dark room is close to 0.

• The recommended lux level for different activities varies, for example, reading requires around 300-500 lux.
