circuit basics
What is a switch used for
To start and stop the flow of electrons
What are all the elemnts needed for a circuit that moves in a single loop
Battery, wires, Light bulbs/resistors.
What is the name of the board we used in class
Breadboard
What is ohms Law
V = I x R
Calculate the equivalent resistor is a circuit in series with resistors 10,2,3 ohms
15 ohms
What circuit has the same current but different voltage
Series
How to draw a parallel circuit with 1 light bulb and 1 resistor
must have a split
Does it mater which color wires you use on a breadbaord
No
How would you find the amps of a circuit
V / R
What is an equivalent resistor
total electrical resistance in a circuit.
What are the 3 major components needed to complete a circuit
Power source, wire, light/resistor.
How to draw a circuit in parallel with 3 resistors a battery and a light bulb
Explain (with splits)
How many holes are in a row on a breadboard
6
What is the voltage of a wire when the current is 0.05 Amps and the resistance is 200 ohms
10 V
What is the formula of equivalent resistors in series
R1 + R2 + R3
Which type of circuit does voltage stay the same
parallel
What are the blue and read lines in a breadboard
+ - rails that supply power to a circuit
How do you calculate resistance
R = V / I
electrical lights will not come on unless the electrical circuit is a
closed circuit
How do you draw parallel circuits with 2 batteries 5 light bulbs and 3 resistors
draw
what is inside the breadboard?
sets of 5 metal clips
