Characteristics of a Series Circuit
- In a series circuit, the current is consistent throughout all components, meaning the same amount flows through each part.
- The relationship between voltage, current, and resistance is defined by the formula: Current (I) = Total Voltage (V) / Total Resistance (R).
- Total resistance in a series circuit is calculated by adding together the individual resistances of each component, resulting in R_total = R1 + R2 + R3 + ... + Rn.
- The total voltage provided by the power source equals the sum of the voltages across each resistor; this means V_total = V1 + V2 + V3 + ... + Vn.
- Ohm's law can be applied to calculate the voltage drop across each resistor, indicating how much voltage is consumed by each one during operation.
- The total voltage in a series circuit is equal to the total of all individual voltage drops, reinforcing the principle that energy conservation applies in electrical circuits.
