There is a potential difference (voltage) between two points and a path for electrons to travel from an area of low potential (negative) to an area of high potential (positive). Note the direction of "current flow" is opposite the direction of electron flow. In other words current flows from positive to negative. In a circuit involving only a resistor, the current flowing in the circuit is given by I=V/R where I = current, V= voltage, and R=resistance.

As the total resistance is reduced in a simple electrical circuit the current flow will?
increase
Where are circuits used?
Circuits are used anywhere you want to have an electrical current flow. Without a circuit, you cannot have current flow. Without current flow, you cannot do any work.
Electricity will flow only if an electrical circuit is?
if an electric circuit has potential difference. Electricity will flow only if an electrical circuit is closed.
What is the part of a circuit that connects or disconnects the circuit?
Switches, fuses and circuit breakers are examples of some of the electrical parts which can connect or disconnect a circuit to a source of current. A diode does it for alternating current, but only for one half of each cycle. "Connecting" allows an electric current to flow through the circuit. "Disconnecting" stops an electric current from flowing through the circuit.
Difference between electrical current and electrical charge?
current is the flow of charge.
What does a load do to the flow of electrical current in a series circuit?
A load increases the flow of electrical current in a series circuit. No load, no flow.
How are electrical current and circuits related?
Electrical currents require a circuit to flow. If the circuit is broken, then the electrical current will not flow. A switch is a prime example of this principle. When a switch is off, the circuit is broken. However, when it is turned, the circuit is completed and allows for the electrical current to flow through the appliance.
What constitutes a complete electrical circuit?
A complete electrical circuit occurs when it is possible for electrical current to flow through the electrical devices in it.
The opposition to the flow of electrical current?
In a DC circuit . . . resistance. In an AC circuit . . . impedance.
What is a closed path through which current can flow?
A closed path through which a current can flow is called a circuit. Electric Circuit:)
What is closed path throuth which current can flow?
An electric circuit.
What type of electrical circuit will be broken if a wire breaks?
Current will cease to flow in a series electrical circuit.
What kind of circuit allows a current to flow through?
Any complete circuit. ==== An electrical circuit.
The constant flow of electrons through a complete circuit?
That is called electrical current.
When a switch in an electrical circuit is turned off what will happen?
Closing a switch in an electrical circuit will complete the circuit. The supply voltage will then be applied to that circuit, and current will flow through that circuit.
What is the name for the flow of electrons in an electric circuit?
A flow of electrons in an electrical circuit is called a current, which is the name given to the amount of electrical charge flowing in a certain period of time.Any total quantity of electrical charge is measured in coulombs.Any flow of electrical current is measured in amps.1 amp is equal to a flow of 1 coulomb of electrical charge in one second of time.
What called the flow of electricity?
The flow of electricity is called the current. It is measured in Amps (I).Current is the flow of electrons around an electrical circuit.
