Hardik Batra said:I know the simplification of the circuit. All the three resistor will be in parallel. But without simplification of circuit. I want to know the direction of current.
Hardik Batra said:Here no current would flow through A-R1-B. Because A and C point are directly connected (short circuit ?)
But i want direction of current in this circuit only.
ehild said:As U=RI I can be non-zero even in case U=0 if R=0. Current can flow through a zero-resistance wire even if both ends are at the same potential.
Label on each resistor which terminal is positive (connected to the positive terminal of the battery) and which is negative. The current will flow from + to - through the resistor. Then apply the Node Rule to decide the currents through the shorts.

Nugatory said:You know the voltage at each end of R1, so you should be able to find the size and direction of the current across that resistor as well.
Hardik Batra said:No. I don't know the voltage at each end of R1. How would i get?

You REALLY need to get rid of the labels B and C. They are meaningless and are just confusing you.
AGAIN, reread my post #6.
This is getting old.
Hardik Batra said:I know by redrawing the circuit i will get three resistor and current will distribute to each resistor.
But i want direction of current in this circuit only.
Seishin said:Follow the path of least resistance, GrassHopper!
Each end of each thing connects directly to what other thing ?
If each end of R1 connects directly to , , , No, not giving the simple answer , , ,
Your first post declared that the circuit is simply a parallel circuit , , ,
So why would the currents behave in another manner?
Advanced level question: "What difference does it make to the circuit, how you draw it?"

ehild said:No. At junction B, current flows in both from A and C. So the current must flow outward through the wire connecting B and C. Change the direction of the arrow.
CWatters said:I believe this should read "So the current must flow outward through the wire connecting B and D"
The current direction in a circuit is the flow of electric charge. In most circuits, the current flows from the positive terminal of a power source to the negative terminal.
Current direction is measured in a circuit using an ammeter, which is a device that measures the amount of electric current flowing through a circuit. The ammeter is connected in series with the circuit, and the current flows through it, allowing for accurate measurement.
Yes, current direction can change in a circuit. This can happen if the polarity of the power source is reversed or if the circuit contains components such as diodes, which only allow current to flow in one direction.
The direction of current in a circuit is important for determining the proper functioning of components. For example, electronic devices such as transistors and integrated circuits are designed to work with a specific current direction, and reversing the direction can cause them to malfunction or even be damaged.
Yes, there are exceptions to the typical current direction in a circuit. In some circuits, such as inverter circuits, the current flows from the negative terminal to the positive terminal. Additionally, in alternating current (AC) circuits, the direction of current constantly changes, flowing back and forth instead of in a single direction.
