Parallel and Series circuit

• How are components connected in a series circuit?

  Components are connected end-to-end in a single path.
• What happens to the current in a series circuit?

  The same current flows through all components.
• How is the total resistance in a series circuit calculated?


  The total resistance is the sum of the resistances of all the components.
• What is the formula for total resistance in a series circuit?

  $R_{\text{total}} =$$R_1 +$$R_2 +$$R_3 +$$\ldots$
• What occurs if one component breaks in a series circuit?


  If one component breaks, the whole circuit stops working.
• How are components connected in a parallel circuit?


  Components are connected in separate branches, providing more than one path for the current.
• What is the voltage across each branch in a parallel circuit?

  The voltage across each branch is the same.
• How is the total current in a parallel circuit determined?

  The total current is the sum of the currents through each branch.
• What happens if one component breaks in a parallel circuit?

  If one component breaks, the other branches keep working.
• What is the relationship between total resistance and individual resistances in a parallel circuit?


  The total resistance is less than the smallest individual resistance.
• What is the formula for total resistance in a parallel circuit?


  $\frac{1}{R_{\text{total}}} =$$\frac{1}{R_1} +$$\frac{1}{R_2} +$$\ldots$
