![]() ![]() Reference voltage is taken for nominal comparison of capacitor value.Seesaw is a comparator or an op-amp used for comparing the voltages of capacitor and reference.The bucket can be considered as an energy-storing device which is either a capacitor or an inductor.Now, if we compare the mechanical components with electrical components, then we have. And because of this cycle, the plank moves along the axis with periodic intervals, thereby giving an oscillation output. This cycle of filling and spilling keeps on going up until the water source is present to fill the bucket. So again the plank moves along the axis, thereby shifting the bucket to the air again for another filling. ![]() After the spillage, the total mass on the bucket side will again become less compared to the fixed mass ‘M’. Once the bucket hits the ground, the water filled in the bucket gets spilled over completely to the ground as shown in the figure. So the plank moves along the axis thereby airlifting the Mass ‘M’ and grounding the water bucket. Now, if turn on the tap placed above the empty bucket, then the water starts filling the empty bucket and thereby increasing the mass of the entire setup.Īnd once the bucket gets completely full, then the entire mass on the bucket side will be more than the fixed mass ’M’ placed on the other end. At this initial state the mass ’M’ will be leveled to the ground and the bucket will be hanged in the air based on seesaw principle discussed above. ![]() In this seesaw setup, we will have a fixed mass ‘M’ on one end and an empty bucket on the other end as shown in the figure. So whichever objects has higher mass gets leveled to the ground while the lower mass object is lifted to air. In simple terms, the seesaw is a comparator of ‘Mass’ and it compares the mass of objects placed on both the ends of the plank. Plank moves back and forth depending on the gravitational force experienced by the masses on both ends. The mechanism shown here is a seesaw that everyone probably experienced in their life. The frequency or period of oscillation for such an oscillator depends on the time constant of their respective capacitive or inductive circuit.įor a better understanding of the Relaxation Oscillator, let us first look into the working of a simple mechanism shown below.
