Difference between Latching and Holding of the electric current:
The important point of difference between Latching current and holding current is related between the process of scr because of the switches are turn ON.
The forward biased current is always based on the latching current but the forward bias and positive terminal are remain same.The current in the anode is connected to the continuous selection.Average value and important value are calculated by the less current.
The less Current supply is become more reactive and then control the loss.This current does not Flow in the same direction and signal of this current is always vary .
This will prevent the fall down of current and holding the current supply in same direction.during this holding current minimum value of scr becomes 5mA to stop the conducting materials.
Let us saw the difference between Latching current and holding current
| Sr. No. | Latching Current | Holding Current |
| 1) | This is depend on the switches on procedure. | This is depend on the switches OFF procedure. |
| 2) | It control the minimum value of current loss. | It control the minimum value and above current loss. |
| 3) | Holding current value is less than that of latching current. | It is more than that of latching current. |
| 4) | Latching current is generally 2 to 3 times of the holding current. | It is more reliable to the latching current. |
latching current and holding current difference
In electric circuits, current flows through a wire from the power source to the load. If you want to turn off the current flowing through a wire, you need to latch the current and hold it until you turn off the power. Latching current and holding current difference is an important concept in electric circuits. Let’s look at an example.
What is Latching Current?
Latching current is the ability of a device to maintain a constant current supply when it is switched off and then switched back on. It prevents the device from briefly drawing more current than it can deliver, which can cause damage.
The most common use for latching current is in power supplies, where it helps protect against overloads and prolonged brownouts. Latching current also plays a role in some medical devices, such as heart pacemakers and defibrillators.
How does Latching Current Work?
When you turn off a device, its switching circuitry momentarily disconnects the power supply from the device’s electrical contacts. This allows the device’s internal battery to discharge slowly over time (called “drift”), which reduces the risk of short-circuiting or damaging the device. After a certain amount of time has passed, the switching circuitry reconnects the power supply and starts supplying current again. Because the current is constantly supplied, the device remains powered even if you switch it off and then switch it back on quickly (called “latch-up”).
What is Holding Current?
When a current flows through a circuit, it moves electrons through the wire. The speed of the current is determined by how much resistance is in the circuit. When you connect two wires together, there is now more resistance in the circuit. This means that the speed of the current is decreased. The amount of current that can flow through the circuit is called “holding current”.
The holding current is what keeps your batteries from going dead when you forgot to turn your flashlight off. It’s also what powers your computer when you plug it in to your charger. The holding current is what allows voltage to exist on electrical circuits.
Why Would We Want to Hold Current?
There are a few reasons why you might want to hold current. One reason is that you might want to avoid sparking across a delicate wire or circuit, which could cause a fire. Another reason is that you might be trying to charge a battery using a current that is too high for the battery to handle. Finally, holding current can help prevent AC voltage from collapsing (or “flashing”), which can damage components.
How to Latch Current and Hold Current
The purpose of this article is to provide the reader with information on how to latch current and hold current differences. By understanding these concepts, the reader will be able to safely work with currents greater than 60A.
When starting a piece of equipment, it is important to ensure that the proper current is flowing through it. Too much or too little current can damage the equipment or even kill someone. To ensure that the proper current is flowing, it is necessary to latch current and hold current differences. Latching current refers to connecting two pieces of equipment together and turning on the power. When you latch current, you are telling the devices that are connected that they should start working together as a unit. This allows you to control the flow of power more easily. Holding current refers to keeping the amount of current flowing through a piece of equipment constant. This is done by using a switch or circuit breaker. When you use a switch or circuit breaker, you are telling the equipment that is connected not to change the amount of current that is flowing through it. This keeps the devices from getting confused and saves you time and trouble.
Conclusion
In this article, we will be exploring the difference between latching current and holding current. We will also look at how to latch current using a power supply and how to hold current using an inductor. Finally, we will explore some applications of these concepts.
