Study Notes
Kirchhoff's Laws
- Kirchhoff's Current Law (KCL): The sum of all currents entering a node in a circuit is equal to the sum of all currents leaving the node.
- Kirchhoff's Voltage Law (KVL): The sum of all voltage changes around a closed loop in a circuit is equal to zero.
Energy Storage in Capacitors
- The energy stored in a capacitor is given by the expression: U = (1/2)CV^2, where U is the energy, C is the capacitance, and V is the voltage across the capacitor.
- This energy is stored in the electric field between the capacitor plates.
Energy Storage in Inductors
- The energy stored in an inductor is given by the expression: U = (1/2)Li^2, where U is the energy, L is the inductance, and i is the current through the inductor.
- This energy is stored in the magnetic field around the inductor.
Ideal and Real Current Sources
- Ideal Current Source: A current source that provides a constant current, regardless of the voltage across it, represented by an arrow pointing to the negative terminal.
- Real current sources have internal resistance, which affects the output current, and can be represented by an ideal current source in parallel with a resistor.
Ideal and Real Voltage Sources
- Ideal Voltage Source: A voltage source that provides a constant voltage, regardless of the current drawn from it, represented by an arrow pointing to the positive terminal.
- Real voltage sources have internal resistance, which affects the output voltage, and can be represented by an ideal voltage source in series with a resistor.
