Electric circuitsOnline version Practice a little with the contents about electricity we have seen in class by Mónica Garrido 1 Two generators are connected in series when a Their positive terminals are connected. b Their negative terminals are connected. c The positive terminal of the first generator is connected to the negative terminal of the second one. d All the other answers are correct. 2 The total voltage of various equal generators connected in parallel is a None of the others b The result of multiplying the voltage of each generator. c The result of adding the voltage of each generator. d The same voltage of just one generator. 3 The more receivers in parallel connected to a generator a The lower the voltage received by each of them. b The higher the electric current (intensity) the generator should provide. c The longer the operating time the batteries will have (they will last more). d The higher the voltage the battery will provide 4 Select the correct circuit diagram a A b B c C d D 5 In the following circuit, calculate the equivalent resistance a 30 b 90 c 20 d 45 6 Select the correct circuit diagram a A b B c C d D 7 Calculate the total resitance of the whole circuit (RT) Written answer 8 Calculate the intensity (electric current) provided by the battery Written answer 9 Calculate the partial intensities a I1=0.05A, I2=0.05, A I3=0.05A b I1=0.15A, I2=0.15, A I3=0.15A c I1=0.15A, I2=0.15, A I3=0.05A d I1=0.1A, I2=0.1, A I3=0.05A 10 Calculate the partial voltages. a V1=9V, V2=9V, V3=9V b V1=3V, V2=3V, V3=3V c V1=3V, V2=6V, V3=9V d V1=2.25V, V2=2.25V, V3=4.5V
