A thermal Fuse or Thermal Cutoff is a Safety Device That Open Circuits Against overheating. It Detects the Heat Caused by the Over-Current Due to Short Circuits or Component Breakdown. Thermal Fuses do not Reset Themselves when the Temperature drops as a circuit breaker would. A Thermal fuse must be replaced when it fails or is Triggered. Thermal fuses only react to excessive temperature, Unlike electrical fuses or circuit breakers, not excessive Current, unless the excessive current is sufficient to cause the Thermal fuse Itself to heat up to the Trigger Temperature.
Using a transformer, electric energy can be moved from one AC circuit to another. A transformer uses the electromagnetic induction principle to either increase or decrease the AC voltage (step-up or step-down). To lower the power in the circuits of low-voltage devices like doorbells, transformers are frequently utilized.
Single-Phase Single In-Line Bridge Rectifiers.General purpose use in AC/DC bridge full wave rectification for switching power supply, home appliances, office equipment, and industrial automation applications.
The capacitor is a Two-Terminal passive component having the Property of Capacitance. This Property Electrifies (charging with electricity) Capacitors with input Voltage. Capacitors Condense Electricity, Hence it is also known as a Condenser. It consists of two Electrical Conductors that are Separated by Distance. The Capacitor Stores Charge and can act like a Battery. It is necessary for filter Circuits to Minimize voltage spikes, and Smoothing changes in voltage.
