components
what happens when a switch is closed?
it completes the circuit, allowing electrical current to flow through it.
what is the difference between a series and a parralel circuit
A series circuit forms a single path for current flow. A parallel circuit forms multiple paths for current to flow through.
What does DC stand for?
Direct Current
What does a voltmeter measure?
voltage, which is the electrical potential difference between two points in an electrical circuit.
What is the same for all components in a parallel circuit?
The voltage
what is the function of a DC power supply?
provides a stable source of direct current to power electronic circuits, devices, and systems.
what does an Ammeter measure?
the electric current flowing through a circuit.
How does the total resistance in a parallel circuit change when you add more resistors?
It decreases
what is the function of an AC power supply?
heavy-duty industrial equipment and electric motors
what is the difference between a resistor, and a variable resistor?
a resistor has a fixed resistance value, while a variable resistor's resistance can be adjusted.
If one bulb in a parallel circuit burns out, what happens to the other bulbs?
It stays lit
what happens when you combine the two values?
When combining AC and DC values, the resulting waveform is a level-shifted AC waveform.
what is the difference between a dc power supply and ac power supply?
AC power supply current periodically reverses direction, while DC power supply current flows in one direction only.
When is AC used in a Circuit?
transmitting electricity over long distances and powering household appliances.
What does AC stand for?
Alternating Current
