What is an electric circuit that controls another electric circuit through a relay?
Remote-Control Circuit. Any electrical circuit that controlsany other circuit through a relay or an equivalent device.
What does a potentiometer do?
A potentiometer varies the amount of current through an electrical or electronic circuit. EX: the volume control on your radio is a potentiometer. In today's electronic circuitry, digital circuits that change resistance do the same job as the rotary type control do. They tend to be more accurate.
Many circuits have a which is a device to open and close the circuit.?
A basic manual operating switch is able to open or close a circuit. There are electronic components that will also control the working of a circuit.
What term best describes an electrical circuit in which no current flows from the power source through the control component load and conductors?
A cold circuit
What is the definition of the consumer circuit in electrical installation?
Consumer circuit is a circuit that fixed between distribution line and consumer load control and protection unit is attached in order to prevent overload, leakage and short circuit.
What is the function of a carbon pile resistor in an electrical circuit?
A carbon pile resistor is used in electrical circuits to control the amount of current flowing through the circuit by adjusting its resistance. This helps regulate the voltage and prevent damage to the components in the circuit.
How do resistors work and what is their role in an electrical circuit?
Resistors are electronic components that limit the flow of electric current in a circuit. They work by converting electrical energy into heat. Their role in an electrical circuit is to control the amount of current flowing through different parts of the circuit, helping to regulate voltage levels and protect sensitive components from damage.
How do resistors affect the flow of current in an electrical circuit?
Resistors in an electrical circuit limit the flow of current by impeding the movement of electrons. They reduce the amount of current that can pass through a circuit, which helps control the voltage and prevent damage to components.
What is the point of a resistor in an electrical circuit?
A resistor in an electrical circuit is used to control the flow of electric current and reduce the amount of voltage in the circuit. It helps regulate the amount of current that flows through the circuit and protects other components from damage due to excessive current.
What is the function of a carbon pile rheostat in an electrical circuit?
A carbon pile rheostat is used to control the amount of electrical current flowing through a circuit by varying the resistance. It works by adjusting the amount of contact between carbon discs, which changes the resistance and therefore the current flow.
What are electric panels?
Usually electrical panels are metallic enclosures that house electrical components. An electrical home panel contains the house's circuit breakers. An electrical control panel contains electrical controls such as relays that usually control other pieces of machinery or motors.
What is the purposed of resistance in the circuit?
Resistance is generally used to control the flow of amount of current in the circuit.
How does a resistor work to limit the flow of electric current in a circuit?
A resistor limits the flow of electric current in a circuit by providing resistance to the flow of electrons. This resistance reduces the amount of current that can pass through the circuit, helping to control the flow of electricity and prevent damage to components.
How do resistors work in an electrical circuit?
Resistors work in an electrical circuit by limiting the flow of electric current. They are designed to resist the flow of electricity, which helps control the amount of current passing through a circuit. This resistance is measured in ohms and can be adjusted by changing the value of the resistor.
What is a device that can control the current in a circuit?
A variable resistor can be used to control the current in a circuit by adjusting its resistance. By changing the resistance value, the amount of current flowing through the circuit can be regulated.
What does a variable resistor diagram illustrate?
A variable resistor diagram illustrates how a resistor can change its resistance value, allowing for adjustable control of electrical current in a circuit.
Is a circuit breaker a resistor?
No, a circuit breaker is a safety device that is used in a circuit to limit the amount of current in an overload or short circuit condition. The number on a breaker is the top end current that the breaker will handle before opening the circuit.
