The lightbulbs in figures 1 and 2 have resistances of R; = 10.022, R = 15.00 and Rs = 20.00 What is the equivalent resistance between A and B for figure 1? OIL10 O 7.80 O 26.00 18.62 Figure 1 The wires between the lightbulbs are rearranged as shown in figure 2 What is the equivalent resistance between A and B now? O 1112 O 2600 18.60 780 Figure 2 A steady electric current flows through a wire. If 6.0 C of charge passes a particular spot in the wire in a time period of 4.05. what is the current in the wire? O 0.67 A O24A O 15A O 6.0 A If the current is a constant 4.0 A, how long will it take for 14.0 Corcharge to move past a particular spot in the wire? 565 O 3.5 s O 0.29 14.05
