1. Here are some statements about conventional current. Which three are true? *

1 point

Conventional current is the flow of positive charges

Conventional current is sometimes the flow of negative charges

Conventional current flows in the sense positive to negative

Electron flow is an example of conventional current

If negative charges are flowing then we imagine ADDING positive charges flowing in the opposite direction

If negative charges are flowing then we imagine REPLACING them with imaginary positive charges flowing in the opposite direction

Required

2. True or False? Our circuit simulation shows conventional current. *

1 point

True

False

3. Why do we use conventional current, despite electrons in wires flowing in the opposite direction? Choose three. *

1 point

Electric currents can also be the flow of positive charges, for example ions in liquids, so electron flow is just a special case of currents in general

We could easily change to electron flow without affecting any other parts of physics

Batteries would stop working if we changed our convention to electron flow

The actual direction of the current is rarely important, because electric charges all start moving everywhere at the same time

It doesn't matter about the convention, as long as everyone agrees to use the same one
