Draw Schematics

Which of the following statements are true when Drawing Schematic Diagrams?
The symbols used will change for different countries
Use the same orientation for all component labels
All circuits need a resistor
All wires must be straight lines
You can draw a curved line for a wire only it was actually curved in real life
Current flows from the positive end of a source to the negative
Connections between components are marked with a dot
[FALSE]The symbols used will change for different countries
you use standardized symbols
[]Use the same orientation for all component labels
i don’t quite get the question
[FALSE]All circuits need a resistor
some transistor circuits have no resistors
[TRUE]All wires must be straight lines
i’ve never seen a proper Circuit Diagram with curved lines
[FALSE]You can draw a curved line for a wire only it was actually curved in real life
not really
[TRUE]Current flows from the positive end of a source to the negative
current flows from positive to negative, but the electrons flow in reverse
[TRUE/FALSE]Connections between components are marked with a dot
some Schematics do have a dot but some don’t, there’s no direct rule for this
