Digital Stopwatch Circuit Principle: This circuit is based on the principle of 2 stage counter operation, based on synchronous cascading. The idea is to display clock pulses count from 0 to 59, representing a 60 second time interval. This is done by using a 555 Timer IC connected in astable mode to produce the clock pulses of 1 second interval each. While the first counter counts from 0 to 9, the second counter starts its counting operation every time the count value of first counter reaches 9....

Consider a task of moving a charge from A to B in a uniform electric field. Let this movement be against to the electric field. Some work will be done by an external force on this charge and this work will change the potential energy to a higher value. The amount of work done is equal to the change in potential energy. This change in potential energy will result in a difference in potential between the two points A and B....
