Answer 2

2 ranges to this. First artwork out the present it particularly is flowing during the circuit - that's the commonest electric equation - Ohms regulation Volts = present day x Resistance (V = I x R) I = V / R put in the numbers: I = 2 / 2000 or a million / one thousand Now use your hint P = V x I and positioned the numbers in back P = 2 x a million/one thousand P = 0.002 W m ability milli and that's a million/one thousand, so multiply your answer by one thousand and upload 'm' to 'W' to get P = 2mW, Aha!! answer B
