Why do electric cells have 2 terminals?
Electric cells have two terminals, a positive (+) and a negative (-), to facilitate the flow of electrons in a circuit. Electrons are released at the negative terminal and flow through the circuit to the positive terminal, creating an electric current. Having two terminals allows for the creation of a potential difference, which is essential for generating electricity.
How can you measure electric potential and electric current?
Potential . . .Always measured as a potential difference between two points.The most practical way to do that is with a voltemeter connectedin parallel with any circuit between the two points.Electric current . . .The most practical way to measure current is with an ammeter connectedin series in the path of the current.
What makes up an electric circuit?
What components make up an eletrical circuit
What two parts of an electric circuit are show in the picture?
Since we cannot see the picture... we cannot help you !
What is the Point of Connection in an electric circuit?
TerminalOr...'Point of connection' refers to the interface between the utility company's equipment (main fuse, energy meter) and the consumer's equipment (supply panel).
What is an electric circuit with two or more path?
Is a parallel circuit whit 2 or more wires
What is the relationship between the electric field formula and voltage in an electric circuit?
The electric field formula and voltage in an electric circuit are related because voltage is a measure of the electric potential difference between two points in a circuit, and the electric field is the force that causes charges to move between those points. In simple terms, the electric field creates the voltage that drives the flow of electric current in a circuit.
What 3 terms are used to describe electric pressure?
Voltage: This measures the electric potential energy between two points in a circuit. Electromotive force (EMF): It represents the push that drives the electric current in a circuit. Potential difference: This is the difference in electric potential between two points in a circuit, causing the flow of current.

What is electrical splice?
The joining together of two or more conductors in an electric circuit.
Why is there no flow of electric current?
There are two possible causes: 1. The circuit has no Voltage applied to it. 2. The resistance of the circuit is INFINITE.
What is the difference between a series circuit and as parallel circuit?
series circuit can only move on one patha parallel circuit has two more paths for the electric carve to follow
What is the best definition of voltage?
Voltage is the difference in electric potential between two points in an electric circuit, representing the amount of potential energy available to move electric charge. It is measured in volts and determines the force or pressure that drives electric current through a circuit.
What does volt measure?
Voltage measures the electrical potential between two parts of an electrical circuit. Also called electromotive force. Voltage provides the 'pressure' to drive electrons round a circuit.
What an electric cell is and how it causes a current in an external circuit?
An electrical cell is the basic unit from which electrical batteries are made. The cell is composed of two plates made of different conductive materials and a liquid electrolyte (in "dry" cells this liquid is in the form of a moist paste). Electric charge is produced between the two plates by the electrolyte interacting with and causing corrosion of one or both plates. Once the electric charge is produced the corrosion process slows or stops, unless an external circuit is connected between the plates. When an external circuit is connected between the plates, current flows through that circuit and the electric charge is slightly reduced. The corrosion process continues at a rate necessary to maintain the electric charge, until the chemicals in the cell are used up.
What is the potential difference between two points in an electric circuit?
The potential difference between two points in an electric circuit is the measure of how much energy is needed to move a charge from one point to the other. It is also known as voltage and is measured in volts.
