Inductor
A coil of wire in a circuit that affects the circuit when the current is changing.
Inductance
A property of an inductor, denoted by 'L', that quantifies its ability to induce EMF.
Self-inductance
The phenomenon where a changing current in a coil induces an EMF in the same coil.
EMF
Electromotive force induced in a circuit due to changing current.
Kirchhoff's Loop Rule
A principle stating the sum of voltages around any closed loop in a circuit is zero.
Lenz's Law
A law stating the direction of induced EMF opposes the change in current that created it.
Magnetic Field
A field generated by a current-carrying coil, proportional to the current.
Voltage
The electric potential difference across a component in a circuit.
Resistor
A circuit component that opposes the flow of current, causing a voltage drop.
Battery
A source of electrical energy providing a voltage in a circuit.
Current
The flow of electric charge in a circuit, measured in amperes.
Polarity
The orientation of positive and negative terminals in a circuit component.
Loop
A closed path in a circuit used to apply Kirchhoff's loop rule.
Direction
The orientation of current flow or EMF in a circuit, crucial for applying rules.
Delta I
The change in current over time, crucial for calculating induced EMF.
