What device is used to adjust the flow of electrical current?
A device used to adjust the flow of electrical current is called a resistor.
Electrical device activated by a current that opens or closes another circuit?
An electrical device activated by a current that opens or closes another circuit is called a relay. A contactor also falls into this category.
What is the opposite to a cathode?
A cathode is an electrode through which electrical current exits a polarized electrical device. Its opposite is the anode, through which electrical current enters the electrical device. Positively charged ions, called cations, move towards the cathode, while negatively charged ions, called anions, move towards the anode.
What device creates a potential difference in an electric circuit?
A battery is the device that creates a potential difference in an electric circuit. It establishes an electric field within the circuit that allows charges to move from the positive terminal to the negative terminal, creating an electrical current.
What electrical current flows through electrical home devices?
The electrical current for a home device travels in a circuit.
What is a device that converts mechanical energy into electrical energy called?
A device that converts mechanical energy into electrical energy is called a generator. It uses the principle of electromagnetic induction to produce an electric current when a mechanical force, such as rotation, is applied to it.
What is the current and how is it measured in electrical circuits?
The current in electrical circuits is the flow of electric charge. It is measured in amperes (A) using a device called an ammeter. The ammeter is connected in series with the circuit to measure the current passing through it.
What is the difference between a line wire and a load wire in electrical wiring?
A line wire carries electrical current into a device, while a load wire carries electrical current out of a device.
Why does connecting an electric device to a battery produces a current?
When an electric device is connected to a battery, an electric current is produced due to the difference in potential between the positive and negative terminals of the battery. This potential difference, also known as voltage, creates an electrical force that pushes the flow of electric charge (current) through the circuit and powers the device.
A is a device that produces electricity by converting chemical energy into electrical energy?
The device you are referring to is a battery. Batteries store chemical energy which is converted into electrical energy through a chemical reaction that releases electrons. This flow of electrons creates an electric current that can power various devices.
What is the device that resists the flow of electrical current?
resistor
A device that produces an electric current by converting chemicalenergy into electrical energy?
A chemical cell or strings of cells called a battery.
