A variable resistor can be used to control the current in a circuit by adjusting its resistance. By changing the resistance value, the amount of current flowing through the circuit can be regulated.
A resistor is a device that resists the flow of electricity in a circuit. It is used to control the amount of current flowing through the circuit by providing a specific amount of resistance.
In a parallel circuit, each branch has its own current flow, so there isn't a single device that has the smallest current. The current through each device is determined by its resistance and voltage applied. The device with the highest resistance will have the smallest current flowing through it in a parallel circuit.
A device that reverses the direction of electric current is called a switch or a commutator. These devices can change the flow of current by opening or closing a circuit in the opposite direction. Such devices are commonly used in electrical systems to control the direction of current flow.
A switch controls the flow of electric current by opening and closing a circuit. When the switch is closed, it completes the circuit, allowing current to flow through. Conversely, when the switch is open, it breaks the circuit, stopping the flow of current. This on/off mechanism enables the switch to control the flow of electricity to a device or appliance.
A fuse is a safety device that melts and breaks the electrical circuit if there is excessive current flow, while a switch is a mechanical device that opens or closes a circuit. Both can control the flow of electricity, but the fuse acts as a protective measure against overcurrent situations, whereas the switch is used to manually control the circuit.
A resister limits the amount of current passing through a circuit.
An inrush current preventing circuit includes a rectification circuit, a temperature-sensitive component, a controller, a switching circuit, and a tank circuit. The controller outputs a control signal to turn on the switching circuit in response to the tank circuit being at a substantially full voltage, and the rectification circuit and the switching circuit forming a current loop for providing power from the rectification circuit to an electronic device. The controller outputs no control signal to turn off the switching circuit in response to the tank circuit being undercharged, and the rectification circuit and temperature-sensitive component forming a current loop for providing power from the rectification circuit to the electronic device for protecting the electronic device. the rectification circuit and the switching circuit forming a current loop to provide power from the rectification circuit to the electronic device;wherein the controller does not output a control signal to turn off the switching circuit in response to the tank circuit being undercharged, the rectification circuit and temperature-sensitive component forming a current loop to provide power from the rectification circuit to the electronic device such that an excess amount of current is prevented from flowing to the electronic device
A resistor is a device that resists the flow of electricity in a circuit. It is used to control the amount of current flowing through the circuit by providing a specific amount of resistance.
Yes, a switch is a device that stops and starts current flow in a circuit.
Triac is the current control device.
No, a circuit protection device must open the circuit on a fault current or overload.
transistor is a current controlled device. as the current flows through the base of the transistor , it works like a close switch.
A circuit breaker is a device used to open a circuit if too much current flows through it.
Yes, a circuit can work without a switch if it is designed to be always on or if the components are connected directly without the need for a switch to control the flow of current. However, in many applications, a switch is necessary to control when the circuit is on or off.

In a parallel circuit, each branch has its own current flow, so there isn't a single device that has the smallest current. The current through each device is determined by its resistance and voltage applied. The device with the highest resistance will have the smallest current flowing through it in a parallel circuit.
No, a circuit breaker is a safety device that is used in a circuit to limit the amount of current in an overload or short circuit condition. The number on a breaker is the top end current that the breaker will handle before opening the circuit.
