What does a resistor do in an electric circuit?
Limits current flow and drops voltage.
What component resists flow of current in an electrical circuit?
transistor
Which component slow down the current in circuit?
An inductive load can cause current to lag voltage in an AC circuit. An increase in resistance will decrease amount of current flow.
In a series circuit the is the same at every point?
In a series circuit, components (such as resistors, bulbs, or other devices) are connected end-to-end so that there is only one path for the current to flow. Because there is only one pathway for the current, the same current passes through each component in the circuit. This principle is derived from the conservation of electric charge. Since charge cannot accumulate or disappear in a closed circuit, the current that enters a component must be equal to the current that exits that component. In other words, the flow of current is continuous and consistent throughout the series circuit. Mathematically, this can be expressed as: I_total = I_1 = I_2 = I_3 = ... = I_n Where: I_total is the total current entering the series circuit. I_1, I_2, I_3, ..., I_n are the currents through each individual component in the circuit. It's important to note that while the current remains the same throughout a series circuit, the voltage (potential difference) across each component can vary depending on its resistance or impedance, according to Ohm's Law (V = I * R).
Should an ammeter always be connected in parallel with a component?
No, an ammeter should never be placed in parallel with a component - it should always be placed in series, so that the current through the component is measured.If you place an ammeter in parallel with a component, you create a short circuit around the component. Depending on the rest of the circuit, you could damage the circuit, damage the ammeter, create a fire, etc. You certainly will affect the current through the component, and that is not what you want to accomplish.
What is a resistor What does it do in a circuit?
A resistor is a passive two-terminal electrical component that limits the current flowing in electrical or electronic circuits.
What is the type of circuit that will not work when a component burns out?
In a series circuit, if one component burns out, the circuit will not work because the current flow is interrupted by the burnt-out component. This is because components in a series circuit share the same current.
What type of component can amplify the current in a circuit?
A transistor, working in active mode, can amplify a current in a circuit.
Does it matter were we put the switch in a series circuit?
Yes, the placement of the switch does matter in a series circuit. Placing it before a component will interrupt the flow of current to the entire circuit, while placing it after a component will only interrupt the current to that specific component.
Why does the current immediately increase in current after reaching a certain voltage rather than a gradual current increase?
It depends on the nature of the circuit. In a purely-resistive circuit, the current would rise immediately because resistance merely limits its value, it doesn't oppose any change in current. But in a resistive-inductive circuit, for example, the inductive component opposes any change in current, so the current will rise more gradually.
What happens if one of the components in a series or parallel circuit i removed or is defective?
In a series circuit, if one component is removed or defective, the circuit will be broken and no current will flow. In a parallel circuit, if one component is removed or defective, the current will simply bypass that component and continue to flow through the other branches.
How does series circuit travel?
In a series circuit, the electric current flows through each component in sequence. This means that the current passes through one component before moving on to the next one. If one component fails or is removed, the circuit becomes open and no current can flow.
What does a resistor do in an electric circuit?
Limits current flow and drops voltage.
What does a resistor do in a electrical circuit?
Limits current flow and drops voltage.
What are the differences between a parallel and a series circuit?
In a parallel circuit, each component has its own branch and receives the full voltage of the circuit. If one component fails, it does not affect the others. In a series circuit, all components are connected in a line and share the same current. If one component fails, it can disrupt the flow of current to the others.
Will a circuit component with a high resistance will have a low electric current?
Yes
What component resists flow of current in an electrical circuit?
transistor
