Electricity Basics

What is the flow of electricity?

• Electricity flows from the negative terminal to the positive terminal of a power source.

• Electricity flows based on the color of the wires.

• Electricity flows from the positive terminal to the negative terminal of a power source.

• Electricity flows in a circular motion within a power source.

Name two types of electricity.

• 1. Direct Current (DC) 2. Alternating Current (AC)

• Static Current

• Constant Current

• Dynamic Current

How is electricity generated in a hydroelectric power plant?

• By harnessing wind energy to turn turbines

• By burning coal to heat water and produce steam

• By releasing water stored in a reservoir through turbines connected to generators

• By using solar panels to convert sunlight into electricity

What are the sources of renewable electricity?

• Coal, nuclear, oil

• Natural gas, coal, nuclear

• Solar, wind, hydro, geothermal, biomass

• Tidal, wave, fossil fuels

Explain the concept of alternating current (AC).

• AC is an electric current that reverses direction periodically.

• AC is a type of direct current (DC)

• AC flows in one direction only

• AC does not change direction periodically

What is the difference between series and parallel circuits?

• The size of the components

• The main difference between series and parallel circuits is how components are connected and how current flows through them.

• The color of the wires used

• The temperature at which they operate

How is electricity generated in a wind turbine?

• Wind creates a magnetic field that generates electricity directly

• Electricity is produced by the friction of wind against the turbine blades

• Solar panels on the turbine convert sunlight into electricity

• Wind turns the blades of the turbine, which spins a generator inside the turbine to produce electricity.

What are the sources of non-renewable electricity?

• Biomass and tidal power

• Coal, natural gas, oil, and nuclear power

• Solar power and wind power

• Hydropower and geothermal power

How electricity is transported to our homes?

• Through cables

• With batteries

• With a turbine

• With a generator

Define the term 'voltage' in electricity.

• Voltage is the speed of electric current flow.

• Voltage is the resistance in an electrical circuit.

• Voltage is the unit of power consumption.

• Voltage is the difference in electric potential between two points, measured in volts.
