As we know that opamps working on a dual power supply and both power supply should be in the same polarity. If the power supply is not similar in both the polarity the dc output will drift to either side depending on the higher amplitude of polarity and sometimes the case is like this offset nulling will become difficult to achieve So what is "offset nulling" ? Please explain

A load can be considered to be capacitive, resistive or inductive in nature.a) Discuss the differences between these types of loads. Your discussion should include the following: A description of the type of the load and why it is considered to be capacitive, resistive or inductive. How/whether energy is stored. An example where possible, and a comment on how common that type of load is. How the load will respond to a sudden removal of the driving voltage.
