If you think about that situation, it''s clear that no water flows from the upper lake to the lower one because there''s no path for it to get there. The same goes for current: when
AI Customer ServiceIf the wire is connected to a 1.5-volt battery, how much current flows through the wire? The current can be found from Ohm''s Law, V = IR. The V is the battery voltage, so if R can be
AI Customer ServiceIt is important to note that the potential difference across the terminals of the real battery is only equal to the potential difference across the ideal battery if there is no current
AI Customer ServiceIf you only had one ground wire going to the battery, it could create a voltage drop and cause problems with those devices. However, there is no scientific evidence to support this claim, so it is up to you whether or not you want to
AI Customer ServiceOhm''s law applies only for the current flow through a resistor and the voltage across it.When there is no current flow Ohm''s law is not at all applicable.Ohm''s law is not a
AI Customer ServiceThe easiest way to think of it is this: Current will only ever flow in a loop, even in very complex circuits you can always break it down into loops of current, if there is no path for

AI Customer ServiceThe motion of charge carriers (like electrons) is current. If we have a current, then there is a net motion of charge carriers. Really they are swarming all over, much as the individual water molecules are swarming
AI Customer ServiceIf it were a real battery it would have some internal resistance, so simply add the internal resistance to the total resistance of the circuit, in your case the resistance of the wire and calculate the current the way you did it
AI Customer ServiceAn electric current can flow in the wire from one end of the battery to the other, but nothing useful happens. The wire just gets very hot and the battery loses stored internal energy –...

AI Customer ServiceIf only one end of the wire is hooked up to the battery, then there is no potential difference, and no current. You can''t discharge a battery by connecting only one terminal to
AI Customer ServiceA series circuit has all the components in one loop connected by wires, so there is only one route for current to flow. of a circuit eg a battery, motor, lamp, switch or wire. in series they
AI Customer ServiceWe have series circuits and parallel circuits. Now in a series circuit, all the electrical components are connected by wires in one loop. So there''s only one route for the current to flow.
AI Customer ServiceWhen a battery or power supply sets up a difference in potential between two parts of a wire, an electric field is created and the electrons respond to that field. In a current-carrying conductor, however, the electrons do not all flow in the same direction.
If the connecting wire has no resistance or almost zero resistance then it will be a short circuit and a huge current will flow only limited by the internal resistance of the battery. If the electrodes are connected by a conductor through a resistance then the current will be limited according to the Ohm's law.
Maybe something like "Current flow in batteries?" Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics.
If you hook one end of a wire up to a battery, there's a little bit of a potential difference: the wire is effectively one plate of a capacitor, and a few electrons flow in to charge it up. Jun 16, 2019 at 5:00
With this analogy, it is plainly obvious why both the positive and negative ends of a battery must be connected in a circuit. If, say, you connect only the negative electrode to ground, there is no current because there is no electricity coming in on the positive electrode that can be pumped out.
1-Current is flow of electrons . Electrons will only move only and only if there is a potential difference between the ends of a wire . This case also applies to battery as the positive end is maintained at a higher potential than that of negative terminal . Also if you connect an end of a 1km long wire to battery and ground the other end .
