Forensic science is the application of science to law. Any science can be applied into a legal situation, but some of the commonest forensic sciences include forensic biology, forensic chemistry, and forensic toxicology.In order to be a forensic scientist you must first be a scientist.Hon) in pharmacy or biochemistry. Many scientists in the forensic lab have higher qualifications. You will note that these people have science degrees not degrees in forensic science. You cannot apply science to law without knowing the science first.
When dealing with realistic AC circuits, the power is given by $$ P=I\ V\ \cos(\phi), $$ where $\phi$ is the phase difference between the current and the voltage. The unit kVA is a unit of what is called 'apparent power' whereas W is a unit of 'real power'. Apparent power is the maximum possible power attainable when the current and voltage are in phase and real power is the actual amount of work which can be done with a given circuit. share|improve this answer.
Unity is practically present in DC circuits, which creates no difference between the kVA and kW. The relationship between the three (kVA, kW, and Power Factor) is mathematically described as. KW = kVA x Power Factor;
