What is the effect of increasing resistance in a circuit?
Decreases the current flow, assuming voltage remains constant (Ohm's Law).
What happens if the total current entering a junction is not equal to the total current leaving?
It violates Kirchhoff's Junction Rule and the Conservation of Charge, indicating an error in circuit analysis or a fault in the circuit.
What happens when a capacitor is connected in parallel with a resistor?
The capacitor charges up to the voltage across the resistor, storing electrical energy.
What is the effect of increasing the voltage in a circuit?
Increases the current flow, assuming resistance remains constant (Ohm's Law).
What happens if charge is not conserved in a circuit?
The circuit will not function correctly or safely, potentially leading to unpredictable behavior or damage.
What happens when a switch is closed in a circuit with a capacitor?
Charge flows to the capacitor until it is fully charged.
What is Kirchhoff's Junction Rule?
The total current flowing into a junction equals the total current flowing out of that junction.
What is Conservation of Electric Charge?
Charge can't be created or destroyed, only moved around.
Define Electrical Circuit.
A closed loop of components that allows current to flow.
What is Current (I)?
Flow of charge, measured in Amperes (A).
Define Voltage (V).
Potential difference, measured in Volts (V).
What is Resistance (R)?
Opposition to current flow, measured in Ohms (ฮฉ).
What is Capacitance (C)?
Ability to store charge, measured in Farads (F).
Define Inductance (L).
Property of a conductor to induce EMF, measured in Henries (H).
What is Circuit Analysis?
The process of studying and analyzing the behavior of electrical circuits.
How do you apply Kirchhoff's Junction Rule?
1. Identify the junction. 2. Sum the currents entering the junction. 3. Sum the currents leaving the junction. 4. Set the sums equal to each other: $\Sigma I_{in} = \Sigma I_{out}$.
What is the process of analyzing a complex circuit?
1. Simplify the circuit using series and parallel combinations. 2. Apply Kirchhoff's laws to determine unknown currents and voltages. 3. Solve the resulting equations.
