- In practical voltage-source circuits, the load impedance can be too small, forcing the op-amp into current limiting with resulting distortion. Are there similar limits in the current-source circuits?
Homework Answers
we know that Current (I) is inversely proportional to Z...when we have a voltage source there arises of high current problems due to low impedance paths......but when current sources are equipped we control the circuit by controlled current sources like convertors or invertors.
Thus coming to current souces over voltage sources those limitations are reduced . But Current sources being expensive than voltage sources those used at situations where specified tasks have to done and the cost is no matter.
