What else can I help you with?
A switch is a device that stops and starts current flow in a circuit?
Yes, a switch is a device that stops and starts current flow in a circuit.
How do you prevent the excess amount of current flows through the source?
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
True or false A device that is used to open the circuit when the current flow is to great is a disconnect switch?
False. A device that is used to open the circuit when the current flow is too great is a circuit breaker or fuse.A disconnect switch is a manual device that isolates or turns off the load.
A complete electric circuit includes a voltage source current wires and something to ground the flow of current?
If you ground the flow of current like the last part of your question states you will not have a complete circuit as the circuit will open on a short circuit. To make a complete circuit operate you need a power source, an overload device to protect the conductors of the circuit, conductors to carry the current and a load across the power source which causes the current to flow in the circuit. Leave any one of these things out and you will not have a complete circuit.
What a device that protects an electric circuit from too much current?
Circuit Breakers and Fuses limit the amount of current flowing through the circuit.
What is a capacitive fuse?
A capacitive fuse is a type of protective device used in electrical circuits, specifically designed to protect capacitive loads from overcurrent conditions. Unlike traditional fuses that break the circuit due to excessive current, capacitive fuses can handle the inrush currents often associated with capacitors and provide a more controlled disconnection. They ensure safety and reliability in applications such as power supplies, motor drives, and other electronic equipment. Capacitive fuses are typically rated for specific voltage and current levels to ensure proper functioning within the circuit.
A switch is a device that stops and starts current flow in a circuit?
Yes, a switch is a device that stops and starts current flow in a circuit.
What causes heating effect when current flows?
The resistance factors to the current flow in the circuit is what causes the heating effect in a circuit. This resistance usually comes from the load that is connected to the circuit. For example a baseboard heater is a completely resistive load and the result of the heating of the device can be used to heat a room in the home.
Can a varistor be used as a circuit protection device?
No, a circuit protection device must open the circuit on a fault current or overload.
What device used to open a circuit if too much current flows through it?
A circuit breaker is a device used to open a circuit if too much current flows through it.
What device has the smallest current in parallel circuit?
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 protects a circuit from current overload is called what?
Fuse, Circuit breaker
What are the effects of power on a resistive device?
Current passing through a resistor, et al, causes heat. The heat causes the resistance of said resistor to decrease, which causes current to increase, and the cycle just keeps going until the circuit burns out.
What is an electric circuit with little or no resistance?
A: As current approaches infinity on a device it is known as a current source.
What device used to stop and start the flow of electricity in a circuit is a?
A switch is a device that stops and starts current flow in a circuit.
What is the Simplest protective device for an electric current?
A fuse is the simplest protective device for over current in an electric circuit.
What device uses the voltage in an electrical current?
A voltage, or potential difference, is what causes current to flow through a circuit. So all devices (called 'loads') require a voltage applied to them.
