Why do we still use the conventional current?
In wires the current is always carried by electrons. Even with wires we still use conventional current direction to indicate the flow of positive current. The electrons are still moving in the direction they are supposed to, which is in the opposite direction of the current arrow.
What is the difference between conventional and actual current?
Note: We all know that current is the flow of charges. The main difference between the conventional current and electric current is the direction of flow of charges changes. In conventional current it is from positive to negative terminal whereas it is negative to positive terminal in electric current.
Do cars use conventional current?
The cars move one direction and the holes move the other, just like electrons and holes in a circuit. Because the conventional current flow theory is widely accepted in the automotive industry, it is used throughout this book.
What does it mean by conventional current?
Conventional current or simply current, behaves as if positive charge carriers cause current flow. Conventional current flows from the positive terminal to the negative. In general, analyzing an electrical circuit yields results that are independent of the assumed direction of current flow.
What is conventional current and how does it work?
Conventional current doesn’t say that positives or negatives are really moving. It just says that if real positive charges are flowing then that’s great. If it’s really negatives that are flowing we simply replace them with imaginary positives flowing in the opposite direction.
Why don’t we use electron flow instead of conventional current?
By using conventional current all the time we always make sure that energy is dealt with in a consistent way. If we use electron flow then energy cannot be dealt with in a consistent way.
Why do we only have one lot of current?
We still only have one lot of current because each ion only makes ‘half’ a journey. We have to define current as flowing only in one direction in liquids not in both directions. (If it flowed equally in both directions then it would add up to zero and current would not be conserved around a circuit).
Why does current not flow from one side of a switch?
Current only flows if there is a continuous path from one pole of the battery to the other. If you open the switch, no current will flow anywhere in the circuit. It will not flow from one from one pole of the battery to the lamp. For simple circuits like yours, the current is identical at every point in the circuit.
