series, parallel and series Flashcards
What is a series circuit
A series circuit is a circuit where the components are connected end-to-end, forming a single path for current to flow.
What is a parallel circuit
A parallel circuit is a circuit where the components are connected in multiple paths so that current can flow through more than one route.
How does current behave in series and parallel circuits?
Series: The same current flows through all components.
Parallel: Current splits between branches, depending on the resistance of each branch.
How does voltage behave in series and parallel circuits?
Series: The total voltage is the sum of voltages across each component.
Parallel: The voltage is the same across each branch.
How is the polarity affected in a series circuit?
In a series circuit, the polarity of devices (like diodes) is important because the current flows in one direction only, which means the positive and negative terminals must be correctly aligned.
How is the polarity affected in a parallel circuit?
In a parallel circuit, each branch has the same voltage across it, so polarity must be observed for each device to ensure proper operation (e.g., diodes).
What happens in a simple series circuit containing a diode, resistor, and instruments (like a voltmeter or ammeter)?
Diode: The diode will allow current to flow in only one direction (depending on its polarity).
Resistor: The resistor will limit the current, causing a voltage drop.
Instruments: A voltmeter will measure the voltage across components, while an ammeter will measure the current flowing through the circuit.
What happens in a parallel circuit containing a diode, resistor, and instruments?
Diode: Current will flow through the diode in the direction allowed by its polarity, but the voltage across each branch is the same.
Resistor: Each branch with a resistor will have the same voltage across it, but the current may vary depending on the resistance in each branch.
Instruments: A voltmeter will show the same voltage across all branches, while an ammeter will show the current splitting across the branches.
What is a series-parallel combination circuit
A series-parallel combination circuit is a circuit where some components are connected in series and others are connected in parallel. This allows for more complex control of current and voltage.
How does polarity affect a series-parallel combination circuit
In a combination circuit, polarity must be considered for each component. Devices like diodes need to be correctly oriented based on their position in the circuit (whether in series or parallel) to ensure proper operation.
