What happens to an electric current at a switch?
At a switch, the electric current can be opened (turned off) or closed (turned on) depending on the position of the switch. When the switch is opened, the circuit is broken, and no current flows. When the switch is closed, the circuit is complete, and current can flow through the circuit.
What is required for an electric charge to flow through a wire?
An electric charge flows through a wire when there is a closed circuit that allows the charge to move freely. This requires a power source, such as a battery, and a complete path for the charge to travel along, like a wire or conductor.
When the switch is closed the iron rod becomes an electromagnet?
When the switch is closed, an electric current flows through the iron rod, creating a magnetic field around it. This magnetic field magnetizes the iron rod, turning it into an electromagnet. When the switch is opened, the current stops flowing, and the rod loses its magnetism.
Why must a circuit be closed in order for a current to flow?
A circuit must be closed in order for a current to flow because it helps keep a current flow pass. When the switch is closed on a circuit there is a constant flow. When the switches open the flow is disturbed around the circuit.
What happens to the charge of a wire when a current flows through it?
When a current flows through a wire, the charge within the wire does not change. The charge carriers (usually electrons) move along the wire, creating an electric current, but the total charge remains constant.
What is in a light bulb when it's switch is turned on or connected the electricity flows through what we call?
A closed current
What determines if a circuit is open or closed?
A circuit is considered open if there is a gap in the path for electricity to flow, causing the current to stop. A circuit is closed when there is a complete, unbroken path for the electrical current to travel through.

When a light switch is turned on what travels through the wire?
Current flows through a wire when a light switch is turned on.
What are some things about electricity?
It only flows through a closed circuit.
What is the sequence through which charge flows in an electrochemical cell?

What is the measure of electric charge?
The measure of electric charge is the coulomb (C). It is defined as the amount of charge that flows through a circuit when a current of 1 ampere flows for 1 second.
What is a static switch?
A static switch is a switch that uses the electrostatic current that flows through the human body to power on or off the device.
