6 FAQs about [Current after the battery is directly connected to the coil]
What happens when a battery is connected to a circuit?
When a battery is connected to a circuit, the electrons from the anode travel through the circuit toward the cathode in a direct circuit. The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current.
What happens if there is a difference between a battery and a wire?
If the difference is small, little/no current will flow. This holds true for any wire connected between any two terminals, anywhere. However, current more than likely won't (depending upon the age/use of the battery).
Can a current flow in a battery?
Maybe something like "Current flow in batteries?" Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics.
Why do batteries need to be connected in a circuit?
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.
How is current related to voltage in a circuit?
The electrical current is directly proportional to the voltage applied and inversely related to the resistance in a circuit. To understand how to measure current and voltage in a circuit, you must also have a general understanding of how a circuit works and how its electrical measurements are related. What is Voltage?:
What is the electrical driving force across the terminals of a battery?
The electrical driving force across the terminals of a cell is known as the terminal voltage (difference) and is measured in volts. When a battery is connected to a circuit, the electrons from the anode travel through the circuit toward the cathode in a direct circuit. The voltage of a battery is synonymous with its electromotive force, or emf.
