i'm a little confused about the definition of a load current and bleeder current~ what's the difference between them?
asdf1 said:load current and bleeder currents are both branch currents right? if they're both branch currents, shouldn't they be the same thing?
Load current refers to the amount of current that flows through a load or device that is connected to a power source. It is the current that is used to power the load and perform its intended function. Bleeder current, on the other hand, is a small amount of current that is intentionally allowed to flow through a circuit to discharge any residual or stored energy in the circuit when it is turned off. It is used as a safety measure to prevent electric shock or damage to components.
Load current and bleeder current are related in that they both flow through a circuit, but they serve different purposes. Load current is essential for the operation of the load, while bleeder current is only present to discharge stored energy. They are not directly dependent on each other and can vary independently.
Devices that require a power source to function, such as light bulbs, motors, and electronic devices, use load current to operate. Bleeder current is commonly used in electronic devices with capacitors, such as televisions and computers, to prevent electric shock or damage to components when they are turned off.
Yes, both load current and bleeder current can be controlled. The amount of load current can be adjusted by changing the resistance or impedance of the circuit, while the amount of bleeder current can be controlled by adjusting the value of the bleeder resistor. In electronic devices, the amount of bleeder current is usually fixed by the manufacturer to ensure safety.
Load current poses a risk of overheating and damaging components if it exceeds the maximum current rating of the load. Bleeder current, if not properly controlled, can also cause damage to components by discharging too much energy at once. Additionally, if the bleeder resistor is too small, it can create a shock hazard if touched while the circuit is still energized. Therefore, it is important to properly design and control both load current and bleeder current in a circuit to avoid potential risks.
