**Problem:** Given - V
_{T} = 12V - R
_{1} = 1kW - R
_{2} = 2kW | Determine - I
_{T} - I
_{R1} - I
_{R2} | | |

**Procedure:** 1. Find the total resistance - R
_{T} = R_{1} + R2 - R
_{T}= 1k + 2k -
- R
_{T} = 3kW | |

2. Calculate the total current I_{T} = | V_{T} | = | 12 | = 4mA | R_{T} | 3k | | |

3. Determine the current for each resistor I_{R1} = I_{R2} = I_{T} = 4mA | An important characteristic of series circuits is that the same amount of current flows through each element of the circuit, including the source and all resistors. |

**Solution** - I
_{T} = 4mA - I
_{R1} = 4mA - I
_{R2} = 4mA | |
