Question

Three small lamps are connected to a 15 V battery, as shown in the figure. Assume the battery is ideal (has no internal resistance and given in the figure) and the connecting wires haw no resistance. Unlike most real bulbs, the resistances (given in the figure) of the bulbs do not vary. The switch S is closed. W is the equivalent resistance of this circuit? Answer in units of Ohm 013 (part 2 of 4) 10.0 points W is the total current of this circuit? Answer in units of A 014 (part 3 of 4) 10.0 points W is the current in the 5.4 Ohm bulb? Answer in units of A 015 (part 4 of 4) 10.0 points W is the potential difference across the 5.5 Ohm bulb? Answer in units of V

Explanation / Answer

a)5.5+1/(1/5.2+1/5.4) =8.15 b)i=15/8.15 =1.84 c)1.84*5.2/10.6 =0.90 d)5.5*1.84 =10.12
