Electrical Series Circuits
Calculate total resistance, current, and power in a series circuit with multiple resistors connected to a voltage source.
Series Circuit Rules
- The total current in the circuit is equal to the current in any other part of the circuit.
- The total voltage in a series circuit is equal to the sum of the voltages across all parts in the circuit.
- The total resistance in a series circuit is equal to the resistances of all parts in the circuit.
Key Equations
- Total Voltage: U = U1 + U2 + ... + Un
- Ohm's Law: Un = In × Rn
- Equal Currents: I1 = I2 = ... = In
- Total Resistance: R = R1 + R2 + ... + Rn
- Power: P = R × I²
