1.	Which of the following is not an expression power?(a) P=VI(b) P=I^2R(c) P=V^2/R(d) P=I/RThis question was addressed to me during an internship interview.This intriguing question originated from Power in division Simple DC Networks of Basic Electrical Engineering
Answer» The CORRECT choice is (d) P=I/R Explanation: Power is the PRODUCT of voltage and CURRENT. WRITING I in terms of V, we get P=V^2/R and writing V in terms of I, we get P=I^2r.
