What is difference between electric and electronic?
Sometimes the terms are used interchangeably. But roughly speaking, electric circuits include voltage sources such as batteries, as well as "passive" components, such as resistors, inductors, and capacitors - whereas electronic circuits include those, but also additional components with a non-linear characteristic (i.e., a more complicated behavior), such as rectifying diodes and transistors.
What is reactant of a circuit?
A reactant in a circuit is a component that exhibits reactive behavior, such as capacitors and inductors. These components store and release energy in response to changes in voltage and current, affecting the overall flow of electricity in the circuit.Reactants can impact the phase relationship between voltage and current in AC circuits.
What is the function of electrolytic cell?
The function of an electrolytic cell is to use electrical energy to cause a non-spontaneous chemical reaction to occur. This process involves passing an electric current through an electrolyte solution to produce a chemical change, such as the decomposition of water into hydrogen and oxygen gases.
How do the components in electric circuits affect the electric current?
Components such as resistors, capacitors, and inductors can affect electric current by either impeding the flow (resistors), storing charge (capacitors), or inducing voltage (inductors). These components change the overall characteristics of the circuit, affecting the amount of current that flows through it.
What can you do with an electricscope?
An oscilloscope, also known as an electricscope, is a versatile piece of electronic test equipment commonly used to observe varying signal voltages. It is primarily used to measure voltage, frequency, and waveform shape of electronic signals. Additionally, it can be used to troubleshoot and debug electronic circuits and systems.
How do capacitors work and what is their role in electronic circuits?
Capacitors store and release electrical energy in electronic circuits. They consist of two conductive plates separated by an insulating material. When a voltage is applied, one plate accumulates positive charge while the other accumulates negative charge. This creates an electric field that stores energy. Capacitors are used in circuits for filtering, timing, and energy storage purposes.
What are the most common applications for small capacitors in electronic devices?
Small capacitors are commonly used in electronic devices for filtering noise, stabilizing voltage, and storing energy. They are also used in timing circuits, coupling signals, and smoothing power supplies.
HOW DO FILTERING CAPACITORS WORK?
Filtering capacitors work by smoothing out fluctuations in voltage within a circuit, particularly in power supply applications. When placed in parallel with the load, they charge up during voltage peaks and discharge during dips, effectively reducing ripple and providing a more constant voltage output. This action helps to filter out high-frequency noise and stabilize the voltage, ensuring that electronic components receive a steady power supply. By storing and releasing energy, filtering capacitors enhance the performance and reliability of electronic circuits.
How does a capacitor ladder function in electronic circuits?
A capacitor ladder in electronic circuits functions by storing and releasing electrical energy in a controlled manner. It consists of multiple capacitors connected in series and parallel to filter and regulate the flow of current in the circuit. This helps in smoothing out voltage fluctuations and improving the overall performance of the circuit.
How can nodal analysis be applied to a circuit containing capacitors to determine the voltage distribution across the nodes?
Nodal analysis can be used in circuits with capacitors by treating the capacitors as open circuits during analysis. By assigning nodal voltages to each node and applying Kirchhoff's current law, you can determine the voltage distribution across the nodes in the circuit.
How only capacitors can give smooth ac voltage waveform when used in ac circuits?
Capacitors resist a change in voltage, inversely proportional to their capacitance. As a result, transients in the AC line tend to be filtered out.
Is there a minimum derated voltage that tantalum capacitors should be operated at?
Yes, 1/3
Why electronic circuits work at 24volts?
A circuit is designed to work at a specific voltage and that voltage only.
Do electrical devices that are plugged in but not turned on still consume electricity?
Electronic circuits often contain filter circuits that are ahead of the power switch. These Filters contain capacitors between phase and neutral, so called X-Capacitors and between phase and ground respectively neutral and ground, so called Y-Capacitors. These capacitors in conjunction with the the applied alternating voltage are causing a current to flow. Often built in over-voltage protection circuits have got an capacitance (even if it is low) and are causing a minor current to flow. In the stricht sense even the power cord has got a small capacitance and causes a minor current to flow.
How does a Zener diode work to regulate voltage in electronic circuits?
A Zener diode regulates voltage in electronic circuits by allowing current to flow in reverse when the voltage exceeds a certain threshold, maintaining a constant output voltage. This helps stabilize the voltage and protect sensitive components from damage.
How do voltage dividers work and what is their purpose in electronic circuits?
Voltage dividers work by dividing a voltage into smaller parts using resistors connected in series. The purpose of voltage dividers in electronic circuits is to provide a specific voltage level for a component or circuit, such as setting a reference voltage for a sensor or controlling the biasing of a transistor.
Why you are using rectifiers in electronic circuits?
To convert voltage to DC .*(Direct Current)
