Question

Electric current and its effects flow chart

Answer 1

Answer:

the two requirements of an electric circuit are met, then charge will flow through the external circuit. It is said that there is a current - a flow of charge. Using the word current in this context is to simply use it to say that something is happening in the wires - charge is moving. Yet current is a physical quantity that can be measured and expressed numerically. As a physical quantity, current is the rate at which charge flows past a point on a circuit. As depicted in the diagram below, the current in a circuit can be determined if the quantity of charge Q passing through a cross section of a wire in a time t can be measured. The current is simply the ratio of the quantity of charge and time.

Answer 2

• An electric current is a stream of charged particles, such as electrons or ions, that travels through an electrical conductor or space.
• The passage of electric charge through a surface or into a control volume is measured.
• 622 Charge carriers are moving particles that can be one of several types depending on the conductor.
• In electric circuits, electrons travelling over a wire are typically utilised as charge carriers.
• Electrons or holes in semiconductors might be the culprits.
• In an electrolyte, ions are charge carriers; in plasma, an ionised gas, ions and electrons are charge carriers.
