current in series circuits

• What is meant by a series circuit?

  A circuit with no branches for current flow
• What is an electric current?

  The flow of electrical charge around a circuit
• What happens to electrons when the switch in a circuit is closed?

  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 transferred to light and thermal energy
• How is electric current represented in diagrams?

  Using an arrow
• What is the conventional current direction?

  From positive to negative end of the cell
• 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 the reading of the ammeter in the circuit?

  0.1 amp
• What happens to the current in a series circuit?

  The current is the same all the way around
• What will the current read if measured at any point in a series circuit?

  0.1 amp
• What are the key components of a simple electric circuit?

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

  • No branches
  • Current flows in one path
  • Same current throughout the circuit
• What is the significance of the ammeter in a circuit?

  • Measures current flow
  • Indicates current value in amps
  • Essential for circuit analysis
