Sometimes when our circuit power is ON a big current comes suddenly. This sudden current can damage parts like IC, capacitor and transistor. To stop this we make Slow Voltage Rise Power Supply Circuit. This circuit gives voltage slowly but not full at once. So circuit become safe and work is quite reliable. Circuit Working: […]
