## Series and Parallel Circuits: ### Series - An image of a circuit with two resistors in series. - Current is flowing through the circuit in a loop. - The resistors are labeled 'R'. - The current is labeled 'I'. ### Parallel - An image of a circuit with two resistors in parallel. - The current is flowing through the circuit in a loop. - The resistors are labeled 'R'. - The current is labeled 'I'. ### Solving Circuits: #### Series - **Diagram:** A circuit with a voltage source of 50V and two resistors. - **Resistors:** R1= 10Ω, R2= 3Ω - **Calculations** 1. **Req = R1 + Ra** - Req = 10Ω + 3Ω - Req = 13Ω 2. **I = V/Req** - I = 50V / 13Ω - I = 3.85 A #### Parallel - **Diagram:** A circuit with a voltage source of 50V and two resistors. - **Resistors**: R1 = 10Ω, R2 = 3Ω - **Calculations** 1. **1/Req = 1/R1 + 1/Ra** - 1/Req = 1/10 + 1/3 - 1/Req = (3+10)/30 - 1/Req = 13/30 - 13 * Req = 1 * 30 - Req = 2.31Ω 2. **I = V/Req** - I = 50V / 2.31Ω - I = 21.65 A
