What devices typically use DC current to operate?
cell phones, laptops, desktops, anything that uses a battery. most power supplies convert AC to DC at a regulated voltage and current.
Devices which use semiconductors use current to operate than those which do not use semiconductors?

What devices are based on the magnetic effect of current?
Devices such as electric motors, transformers, inductors, and magnetic-based sensors utilize the magnetic effect of current. These devices rely on the interaction between electric current and magnetic fields to operate effectively in various applications.
How do you build a circuit?
Three main components that are needed to build a circuit will be a power source. This supplies the circuit with a voltage to operate. A load to make the current flow through the circuit, and conductors to join these two devices together to carry the current.
Which device uses AC current to operate?
Most household appliances and electronics use AC current to operate, as AC power is the standard form of electricity provided by power companies. This includes items such as lamps, televisions, refrigerators, and microwave ovens.
What are the differences between AC and DC cables, and how do they impact the performance of electronic devices?
AC cables carry alternating current, which changes direction periodically, while DC cables carry direct current, which flows in one direction. The choice of AC or DC cable can impact the performance of electronic devices based on their power requirements and the type of current they are designed to operate with. Devices that require AC power will not function properly with DC cables, and vice versa. It is important to use the correct type of cable to ensure the optimal performance and safety of electronic devices.
What are three sources of power for control circuit?
Three sources of power for control circuits are batteries, power supplies, and solar panels. These sources provide the necessary voltage and current to operate control devices and components in a circuit.
What does a 9 volt battery do?
It provides a source of power to the circuit, in the form of direct current electricity, at a potential difference of 9 volts.
What Type of current that almost all electronics devices use?
The question is much too vague. Electronic devices can be designed to allow for direct or alternating current. Examples are your home DVD player plugged into the receptacle which is 120 volt alternating current and your ipod which uses battery direct current power. Small portable devices are usually direct current (battery power ). The plug that comes with such devices is for charging the battery. Or the device may internally rectify the alternating current and turn it into dc power.
What is the purpose for chargers?
The purpose of chargers is to provide electrical energy to devices, enabling them to recharge their batteries and operate effectively. They convert alternating current (AC) from a power source into direct current (DC) suitable for the device. Chargers ensure that electronic devices, such as smartphones, laptops, and electric vehicles, maintain their battery life and functionality for optimal performance.
What is a phantom power supply and how does it work in audio equipment?
A phantom power supply is a method of providing power to certain types of microphones that require it to function. It works by sending a low-voltage electrical current through the microphone cable, allowing the microphone to operate without needing its own power source. This is commonly used in professional audio equipment to power condenser microphones and other devices that need additional power to operate effectively.
What kind of electricity does America use?
America uses 60 Hertz (Hz) Alternating Current (AC). Most smaller devices operate on 120 volt current.
