Why you need resistance in series with led?
limit current and avoid having it explode
What is the difference between over current and overload condition?
The term, 'overcurrent', describes either an 'overload current' or a 'short-circuit current'.An 'overload current' is a current that is higher than a circuit's 'rated current'. For example, if you have too many loads plugged into the same circuit, then the resulting current is an 'overload current'.A 'short-circuit current' is a large current resulting when a line ('hot') conductor accidentally makes contact with either a neutral conductor or an earth (ground) conductor.
What is a led resistor?
A LED resistor is a resistor used in conjunction with a light-emitting diode (LED) to limit the current flowing through the LED. It prevents excessive current that can damage the LED, ensuring it operates within its specified voltage and current ratings. The value of the resistor is calculated based on the supply voltage, the forward voltage of the LED, and the desired current. This setup is essential in LED circuits to maintain longevity and functionality.
How does an allenbradley overload relay work 193-EF1A?
The Allen-Bradley 193-EF1A overload relay functions by monitoring the current flowing through the motor circuit. It uses thermal and electronic sensing to detect overload conditions, which occur when the current exceeds a preset limit for a specified duration. When an overload is detected, the relay opens its contacts to interrupt the motor circuit, thereby protecting the motor from damage. The relay can be reset manually or automatically, depending on the specific model and configuration.
Can a CMOS gate adequately drive a common LED?
You will have to check the datasheets for both the CMOS gate and the LED, then if the CMOS gate's rated output current is enough to light the LED you will need to do a little arithmetic using Ohm's law to calculate the resistor to put in series with the LED to limit current and avoid damaging the parts.
Can a capacitor be used as a fuse to limit overload current?
No, a capacitor can not be used as a fuse to limit an overload current condition.
How many amps can an LED take?
An LED typically consumes around 20mA (0.02 amps) of current to operate. Exceeding this current limit can damage the LED.

What is the Function of fuse in an electric circuit?
A fuse places a limit on the amount of current that can be drawn by an electric circuit by opening (blowing or melting) when the current exceeds a preset limit. This protects the circuit and the surroundings from fire or damage in the case of an overload or short circuit.
What is a functoin of a resistor?
esistors restrict the flow of electric current, for example a resistor is placed in series with a light-emitting diode (LED) to limit the current passing through the LED.

Why does a Led have a 470 resistor connected to the LED?
A: That resistor is there to limit the current to the LED it can be any value if the voltage is decreased or increased or no resistor if the voltage across the led is equal to the forward voltage drop.
How do you solve overload current?
Reduce the load.
What are the features of ic 7812?
- Output current in excess of 1A - Internal thermal overload protection - No external components required - Output transistor safe area protection - Internal short circuit current limit - Available in the aluminum TO-3 package
How do you wire a 2V LED to run on 12V?
Light Emitting Diodes (LED) solid state devices are current dependant. LED have ratings for the max current allowed to the LED device. A typical current allowed to a LED is 20ma. Ohms Law is used to determine the resistance required to limit the current to your desired current. The formula is used in this manner: E=12VOLTS the desired current is I = 20ma. R = E/I = 600 ohms. Where E=2 volts dc and I=20ma R= E/I = 100 Ohms.
