Series Circuit

• Resistors may be connected in series, in parallel, or a combination of both series and parallel.
• Electric Circuit - the path on which an electric current flows.
• 2 types of circuit:

  • series
  • parallel
• Series circuit - Contains more than one electrical component connected one after the other in a single path.
• Series Circuit - Current flows in a single path and is the same in all circuit parts.
• What happens if the circuit is broken at any point? - No current will flow
• Current - There is only one path where current can flow and the same in all parts.
• Series current formula:

  𝑰𝑻 = 𝑰𝟏 = 𝑰𝟐 = 𝑰𝟑 ...
• Voltage - The sum of the potential difference across individual components is equal to the potential difference across the entire circuit
• Series voltage formula:

  𝑽𝑻 = 𝑽𝟏 + 𝑽𝟐 + 𝑽𝟑 ...
• Resistor - As more resistors are added in series, the equivalent resistance increases.
• Series resistor formula:

  𝑹𝑻 = 𝑹𝟏 + 𝑹𝟐 + 𝑹𝟑 ...
