Think and Compare 1) The brightness are the same because they are under same voltage and current. 2) A > B > C 3) A > B > C 4a) C > B > A b) The voltages are the same.

Think and solve 2) 12 V / 8 ohm = 1.5 A 3) Branches are of the same voltages as the battery. If A equals to 2, then B should be equal to 4. 4) Resistance = voltage / current 120 V / 6 ohm = 20 A 5) 6 = A x 110 A = 6/110 A = 0.05
