4. All bulbs and batteries in electric circuits of Fig.1 and Fig.2 shown below are identical. Fig. 1 Fig. 2 Compare the current at A in Fig.2 to the current at A in Fig.1. a. The current at A in Fig.2 is the same as the current at A in Fig.1. b. Can't tell without knowing the values of battery voltage and bulb resistance. c. The current at A in Fig.2 is half as large as the current at A in Fig.1. d. The current at A in Fig.2 is twice as large as the current at A in Fig. 1. 5. All bulbs and batteries in electric circuits of Fig.1 and Fig.2 shown below are identical. M B Fig. 1 Fig. 2 Compare the brightness of bulb connected between B and C in Fig.2 to the brightness of bulb connected between B and C in Fig. 1. a. The bulb connected between B and C in Fig.2 is just as bright as the bulb connected between B and C in Fig. 1. b. The bulb connected between B and C in Fig.2 is brighter than the bulb connected between B and C in Fig. 1. e. The bulb connected between B and C in Fig.2 is dimmer than the bulb connected between B and C in Fig. 1. d. Can't tell without knowing the values of battery voltage and bulb resistance. 6. All bulbs and batteries in electric circuits of Fig.1 and Fig.2 shown below are identical. B B (w) Pg 2 Compare the current through the bulb connected between B and C in Fig.2 to the current through the bulb connected between B and C in Fig. 1. a. The current through the bulb connected between B and C in Fig.2 is the same as the current through the bulb connected between B and C in Fig. 1. b. The current through the bulb connected between B and C in Fig.2 is smaller than the current through the bulb connected between B and C in Fig. 1. c. The current through the bulb connected between B and C in Fig.2 is larger than the current through the bulb connected between B and C in Fig. 1. d. Can't tell without knowing the values of battery voltage and bulb resistance.
