Resistance is calculated - R (ohms) - primarily as V (voltage) = I (current) times R (resistance) - V=I*R.

It is calculated to determine voltage and current.

It is measured so that it becomes a known value.

What is the meaning of resistor?

Resistors are one of the three basic electronic components. They restrict the flow of current in an electrical circuit. Fixed resistors have a fixed value of resistance, and are used in almost every electronic circuit for lots of different reasons.


What device protects an electrical circuit?

An example of a circuit protection device is a fuse. Another example is a circuit breaker.


What is downstream in electrical?

The terminology down stream refers to an electrical circuit and where devices are connected into the circuit. In reference to the breaker that feeds the circuit everything is down stream from it. If a GFCI receptacle is added into the circuit as the first device, the GFCI can be wired to allow all of the regular receptacles to be protected down stream from that GFCI. Every device added to the circuit will be down stream from the one that is ahead of it. The only device that will not have something down stream from it will be the last device in the circuit.


What is the simple device that opens and closes an electrical unit called?

A device that opens and closes a circuit is called a switch.


What are all the parts on a circuit board?

to assemble a circuit you just need to connect one end of a wire to the battery and the other to the light bulb ( could be another electrical device) now take an other wire and connect on end of it to the other side of the battery and the other to the other side of the light bulb( or an other electrical device. if your circuit is including a switch this is how you do it: ( you will need three wires for this circuit if you have one electrical device) connect one end of the wire to the battery and the other to the switch.Grab another wire and attach one end of it on the other side of the switch and the other to the electrical device (light bulb). Grab another wire and attach one end of it to the other side of battery and the other to the other side of your electrical device. And there you have it how to assemble a circuit

What are devises run by electrical energy represented as resistors in a circuit?

Do not confuse 'resistance' with 'resistor'. 'Resistance' is a quantity, wheras a 'resistor' is a circuit component. In schematic diagrams, the 'rectangular' (European) or 'zig-zag' (US) circuit symbol represents resistance, not a resistor. The circuit symbol, therefore, is used to represent anyresistive device.


Why are resistors called resistors?

Resistors have resisting power(resists the electric power).Due to having the resistive property, the name resistor is given to such electrical device.

What is circuit component?

A circuit component is a discrete device or physical entity within an electrical circuit that performs a specific function, such as controlling the flow of current, storing electrical energy, or amplifying signals. Common circuit components include resistors, capacitors, inductors, transistors, diodes, and integrated circuits. Each component has unique electrical properties and characteristics that contribute to the overall functionality of the circuit.


What device opens and closes an electric circuit?

A switch is a device that is used to open and close an electrical circuit that is is connected into.


Why do you have to use resistors and capacitors in gadgets and devices?

Because the device needs their electrical properties in order to work.


What are active elements in circuit?

A; Any components that provide gain/loss are active device resistors, capacitors are passive


What is the Difference between circuit and parallel circuit?

A series circuit is one in which the current must pass through all the electrical devices in the circuit in turn. A parallel circuit is one in which the current passes through each electrical device on the circuit following separate, independent path from all other devices on the circuit, one for each electrical device.
