Current flow direction indication in circuit diagrams

In summary, current flow direction indication in circuit diagrams is represented by an arrow pointing in the direction of the current flow. It is important to indicate this direction as it helps in understanding the behavior of the circuit and troubleshooting potential problems. The direction is indicated by an arrow symbol, typically from the positive terminal to the negative terminal of the power source. The direction of current flow can vary in different types of circuits, and it can be determined by looking at the circuit diagram and the placement of components.

Hi all,
I'm having a small question about current flow direction indication in circuit diagrams.
Its shown as current flow from +ve pole to -ve pole, but -ve pole has higher electron concentration (potential) & electrons flow from -ve to +ve.
Whats the logic of showing the direction of current flowing in opposite way.
Hope I have made myself clear.
Waiting for reply.
Thanks.

It is a historical accident and now we're stuck with it.
Back when the rules for electricity flow were worked out, they didn't know about the electrons. Doesn't everyone get told about this?
 

1. What is current flow direction indication in circuit diagrams?

Current flow direction indication in circuit diagrams is a representation of the direction in which electric current flows through a circuit. It is usually depicted by an arrow, with the arrow pointing in the direction of the current flow.

2. Why is it important to indicate current flow direction in circuit diagrams?

Indicating current flow direction is important because it helps to understand the behavior and functioning of the circuit. It also helps in troubleshooting and identifying any potential problems in the circuit.

3. How is current flow direction indicated in circuit diagrams?

The direction of current flow in circuit diagrams is indicated by using an arrow symbol. The arrow points in the direction of the flow, from the positive terminal to the negative terminal of the battery or power source.

4. Is current flow direction always the same in a circuit?

No, the direction of current flow can change depending on the type of circuit. In DC circuits, the current flow is always in one direction, while in AC circuits, the current flow changes direction periodically.

5. Can we determine current flow direction by looking at the circuit diagram?

Yes, current flow direction can be determined by looking at the circuit diagram. The arrow symbol and the placement of components can give us an idea of the direction of current flow in the circuit.
