A transformer is used to change voltage levels, provide electrical isolation, and match impedance between circuits. Just as gears trade rotational speed for torque (or vice versa), a transformer trades voltage for current (or vice versa) while keeping the overall power nearly constant.
A choke is a specific type of inductor designed for one primary purpose: to block ("choke") high frequency alternating current (AC) while allowing direct current (DC) or low frequency AC to pass.
It's a transformer-based device that both matches impedance and converts between balanced and unbalanced configurations.
It's a DC (Direct Current) motor combined with an integrated gear train (gearbox). The motor provides high-speed rotation but low torque. The gearbox reduces the speed (RPM) while simultaneously and significantly increasing the output torque.
An inductor is a passive electronic component that smooths out current flow, stores energy magnetically, and is crucial for handling, filtering, and generating signals based on their frequency. From the power supply in your phone to the tuning circuit in your radio and the motor in your vacuum cleaner, inductors are fundamental building blocks of the electronic world.
This is typically referred as Wireless Charging Coil, which is a type of inductor used in wireless charging systems to store and transfer energy.
Current transformers are used to measure current flow in a circuit while maintaining the original voltage level.
