What current flows in two directions?
A Direct Current There are two main types of current in our world. One is direct current (DC) which is a constant stream of charges in one direction. The other is alternating current (AC) that is a stream of charges that reverses direction.
Can electric current flow in two directions?
Current can only flow in one direction. It’s just a question of which node has the higher voltage. The current will always go from the higher potential to the lower.
What is direction of flow of electric current?
Since electric current is a uniform flow of electrons, its direction is opposite to the flow of electrons. Therefore the direction of electric current in an electric circuit is from the positive terminal to the negative terminal of the battery.
Can current flow in opposite directions?
If only negative charges are moving (like in a metal wire for example) the current arrow still points in the direction positive charges would move IF there was positive charge present. Whenever you see a current arrow, you can be assured that electrons are flowing in the opposite direction.
What is the difference between Fleming’s left hand and right hand rule?
Fleming’s left-hand rule is used for electric motors, while Fleming’s right-hand rule is used for electric generators. Since neither the direction of motion nor the direction of the magnetic field (inside the motor/generator) has changed, the direction of the electric current in the motor/generator has reversed.
Can a current flow in more than one direction?
Not sure I completely understand you examples but the answer to your question is no. Current can only flow in one direction. It’s just a question of which node has the higher voltage. The current will always go from the higher potential to the lower. Consider the current as water flowing in a pipe.
How is the direction of an electric current determined?
But in reality, an electric current is nothing but the flow of electrons. Electrons are negatively charged particles and are attracted towards the positive charge. Also, many experiments have revealed that it is free electrons in a conductor that flows. Negatively charged electrons move from the negative terminal to the positive terminal.
What happens if the current is in the opposite direction?
If the current is in opposite directions, then they will cancel as much as possible and the net current will be in the direction of the sub-circuit current which was higher. I R 1 = 0.0 A This was expected.
Can a current flow from higher to lower potential?
Current will only flow from higher to lower potential, and that point in the conductor cannot be simultaneously higher and lower in potential than its neighbor. It may be a useful analytical method to consider a backwards wave. Read post #9 in this thread.
