Calculate the individual voltage, current and power in series and para

[QUOTE="nickbb12, post: 6540735, member: 694202"] [B]Homework Statement:[/B] A set of 16 party lights were purchased for the patio, 2x of 8 sets of bulbs are in parallel with each other, so if i disconnect one bulb, only half of the lights will go out. When all bulbs are functional they draw 3.2Amps from the 24.0V transformer. I need to determine the voltage across each globe, the current through each globe, the power consumed by each globe and finally, if we had a power board with a circuit breaker rated to flip at 10A, how many sets of lights could I operate before flipping the circuit breaker? Thanks :) [B]Relevant Equations:[/B] V = IR P = IV V = 24V I = 3.2A 16 globes (2x 8 in parallel) (8 globes in series) To determine the voltage I did voltage/number of globes: 24/16 = 1.5V per globe - Not sure if this is correct or not To determine current, I figured out using resistance formulas that the resistance for each set of 8 globes is 15 ohms R = V/I 24/3.2 = 7.5 ohms total resistance 7.5[SUP]-1[/SUP] = 2 * 15[SUP]-1[/SUP] Each set of 8 has resistance of 15 ohms. therefore each globe has an individual resistance of 1.875 ohms, I then used I = V/R to get 0.8A per globe. - Not sure if this is correct or not To solve power I simply did P = IV, 1.5 x 0.8 = 1.2W - Again, not sure if this is correct The last one I'm stumped, no idea how I could figure it out. Thanks in advance for people who reply :) [/QUOTE]
