14+ Short Circuit Protection Circuit Diagram. The open circuit test and short circuit test is carried out to determine the various losses, efficiency and also impedance, resistance and the full load current is measured by the ammeter connected across their secondary winding. The current limiting circuit consists of a transistor q3 and a resistor r5 (approximately 1 ohm) connected between base and emitter terminals of the simple current limiting circuit also has a drawback of large power dissipation across the series pass transistor.
A sort circuit is when electricity is able to bypass the device as shown in the next picture. A short circuit is simply a low resistance connection between the two conductors supplying electrical power to any circuit. Short circuit protection circuit is often a desirable feature to add to power amplifiers or power supplies, for both safety concerns and protection of circuitry.
