current in series circuit

• What happens to electrons in a closed switch of a circuit?

  Electrons flow out of the cell around the circuit
• In which direction do electrons flow in a circuit?

  From the negative end to the positive end
• What energy do electrons carry from the cell?

  Electrical energy
• What happens to electrical energy in the lamp?

  It is converted to light and thermal energy
• How is electric current represented?

  Using an arrow
• What is the conventional current direction?

  From positive end to negative end
• What is the unit of electrical current?

  Ampere
• What is the symbol for Ampere?

  Capital A
• How can current be measured in a circuit?

  Using an ammeter
• What is a key point about current in a series circuit?

  Current is the same all the way around
• What are the components of a simple electric circuit?

  • Cell
  • Lamp
  • Open switch
  • Closed switch
• What are the characteristics of a series circuit?

  • No branches
  • Current flows in one path
  • Current is the same throughout
• What is the relationship between electric current and electrical charge?

  • Electric current is the flow of electrical charge
  • Measured in Amperes (A)
• What happens to the energy of electrons as they flow through a circuit?

  • They lose energy when passing components
  • Energy is transferred to components like lamps
