  - - - The current flowing through all of the resistors in the circuit is the same= 𝐼t=𝐼₁=𝐼₂=...=𝐼n
      - The total voltage delivered by the power source = 𝑉t=𝑉₁+𝑉₂+...+𝑉n
      - The equivalent resistance = 𝑅t= 𝑅₁+𝑅₂+...+𝑅n
    - - The equivalent resistance = 1/𝑅t= 1/𝑅₁+1/𝑅₂+...+1/𝑅n
      - The current of the equivalent circuit = 𝐼t +𝐼₁+𝐼₂+...+𝐼n
      - The total voltage delivered by the power source = 𝑉t=𝑉₁=𝑉₂=...=𝑉n
