What is the difference between series circuit and a parallel circuit?
For parallel circuit , each & every component shares 2 common connections . But for series circuit , each of them share 1 common connection .In electrical , each component has their own amount of current flowing through ( depending on the resistance of each ) and sharing the same voltage drop for parallel circuit . In case of series circuit , each component shares the same amount of current with each other & the voltage drop across each of them is different ( depending on their resistance ) .
Why we use resistance?
the resitance would be used to reduce a voltage amplitude to a level suitable to be used in an application, to limit the amount of current flowing within the circuit , or in some cases the resistor could be used as a heating - effect.
What components are placed in an electrical circuit to control the amount of resistance in circuit?
resistors, variable potentiometers
Why shunt resistance must be small in ammeter?
An ammeter has to measure to current flowing through the circuit. Resistance offers an obstruction to the current flow. So, if the resistance of an ammeter is large , the current measured by the ammeter will be quite less as compared to the actual amount of current flowing through the circuit which is undesirable. If ammeter has zero resistance , then it will give the exact value of current. But this is not practically possible because every material has some value of internal resistance which we can't control. For this reason , ammeter must have small resistance
Why you use inductor?
we use the inductor because it helps the circuit to have an appropriate amount of current, so that the circuit in the appliance will say longer.
What is the ability to regulate the amount of charge flowing in a circuit is?
resistance
What is the ability to regulate the amount of charge flowing in a circuit?
Resistance
Is The ability to regulate the amount of charge flowing in a circuit called resistance?
yes
What does the am meter do in a circuit?
An ammeter measures the amount of current flowing in a 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 lower voltage in an electrical circuit?
Resistors lower voltage in an electrical circuit by impeding the flow of electric current, which causes a drop in voltage across the resistor. This drop in voltage helps regulate the overall voltage in the circuit and control the amount of current flowing through it.
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.
What is a device that resists the flow of electricity in a circuit?
A resistor is a device that resists the flow of electricity in a circuit. It is used to control the amount of current flowing through the circuit by providing a specific amount of resistance.
What is a reactor used for in welders?
A reactor in a welder is used to control the voltage and current output of the welding machine. It helps regulate the amount of electricity flowing through the welding circuit, which is essential for producing consistent and high-quality welds.
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 Clamp-on ammeter measure?
An ammeter measures the amount of current flowing through an electrical circuit. It measures amperage.
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.
