Answer the following using the figure as needed:

Figure

When two identical resistors are connected in series to an ideal voltage source, the current supplied by the source is 2.0 amperes. When these two resistors are connected in parallel to the same ideal voltage source, what is the current supplied by the source? O 8.0 A O 4.0 A O 1.0 A 0.5 A O 2.8 AIn plane transmission grating, the angle of diffraction for second order maxima for wavelength 5 x 10^-7 m is 300. Calculate the number of lines in one meter of the grating surface. 1 x 10^6 lines/m 5 x 10^-5 lines/m 1 x 10^8 lines/m 5 x 10^6 lines/mThe graph in Figure 18 represents the relationship between the potential difference across a resistor and the current through the resistor at a constant temperature.
