Study Notes
Electric Circuits
- Electric circuits are interconnected single circuit elements
- At least one voltage or current source is present
- Arrangement of elements creates new constraints between currents and voltages
- Constraints and element relationships provide the solution
- Analysis is used to understand motors, generators, transformers, transducers, and electronics
- Solutions provide operational information under applied conditions
- Purpose of defining and connecting elements is to analyze electrical devices
Ohm's Law
- Current (I) is directly proportional to voltage (V) if temperature is constant
- V ∝ I
- V = IR (where R is resistance)
- Resistance (R) is the constant of proportionality
Kirchhoff's Voltage Law (KVL)
- For any closed path in a network, the algebraic sum of voltages is zero
- Voltages can be from sources or from current in passive elements (voltage drops)
- Applies equally to constant (DC), time-variable and other sources
