The region around a magnet where the magnetic forces act is the ____.	magnetic field
The south pole of a magnet ____.	attracts a north pole

Does alternating current keeps reversing direction True or false?

Question: 1. True Or False: In Direct Current (DC), The Electric Charge (current) Only Flows In One Direction. Electric Charge In Alternating Current (AC), On The Other Hand, Changes Direction Periodically. The Voltage In AC Circuits Also Periodically Reverses Because The Current Changes Direction.

What type of current reverses its direction of flow at regular intervals?

ALTERNATING CURRENT (AC) – A flow of electrons which reverses its direction of flow at regular intervals in a conductor.

Which uses direct current?

Direct current is used in any electronic device with a battery for a power source. It is also used to charge batteries, so rechargeable devices like laptops and cell phones come with an AC adapter that converts alternating current to direct current.

What current flows in one direction only?

In direct current (DC), the electric charge (current) only flows in one direction. The voltage in AC circuits also periodically reverses because the current changes direction.

Which type of current continuously changes direction?

Alternating current (AC) is an electric current which periodically reverses direction, in contrast to direct current (DC) which flows only in one direction.

Do electrons move back and forth in AC current?

The electrons in an AC circuit don’t really move along with the current flow. Instead, they sort of sit and wiggle back and forth. Alternating current works in much the same way. The electrons initially move in one direction, but then reverse themselves and move in the other direction.

Which direction does current flow in a diode?

forward-bias

Can current flow both ways through an LED?

Light-Emitting Diodes (LEDs) Like standard diodes, LEDs only allow current to flow in one direction, but with a twist!

Why do electrons flow in a galvanic cell?

Galvanic cells harness the electrical energy available from the electron transfer in a redox reaction to perform useful electrical work. The key to gathering the electron flow is to separate the oxidation and reduction half-reactions, connecting them by a wire, so that the electrons must flow through that wire.

Where do electrons flow in a voltaic cell?

Electrons always flow from the anode to the cathode or from the oxidation half cell to the reduction half cell. In terms of Eocell of the half reactions, the electrons will flow from the more negative half reaction to the more positive half reaction.

How does current flow in a galvanic cell?

Hence galvanic cell, electrons flow from anode to cathode through an external circuit.

Do electrons flow through salt bridge?

Because negative electrons are flowing through the wire to the reduction half-cell, positive ions travel through the salt bridge to balance the charge of the solution. The flow of electricity in the circuit is maintained by the electrons moving through the wires and the ions moving through solution.

Why do electrons move to cathode?

Electrons have negative charge, they travel towards oposite (positive) charge because they are electrically attracted to it. Since cathode is negatively charged and anode is positively charged, electrons travel from cathode to anode.

Does the anode lose mass?

During electrolysis, the anode loses mass as copper dissolves, and the cathode gains mass as copper is deposited.

Is a cation positive?

A cation has more protons than electrons, consequently giving it a net positive charge.

Why is it called a cation?

A cation (+) (/ˈkætˌaɪ. ən/), from the Greek word κάτω (káto), meaning “down”, is an ion with fewer electrons than protons, giving it a positive charge. There are additional names used for ions with multiple charges.

Which is not a cation?

Sulfate is an anion, not a cation.

Is N3 a cation or anion?

The ion that has the positive charge is called a cation, while the ion which has the negative charge on it is called as an anion….Comparison Chart.
