**Questions regarding the Complex Circuit //Find voltages Vai and Vah Vai=1.44 and Vah=2.82 Find voltages Vab, Vcd, Vde, Vfg, and Vgh Vab=1.40, Vcd=0.01, Vde=0.00, Vfg=0.00, Vgh= Find voltages Vac, Vbc, Vdf, Veg Vac=0.70, Vbc=2.11,Vdf=0.72, Veg=0.68 How does Veg + Vbc compare with Vbg? Veg+Vbc=2.70, and Vbg= What happens to Vbc if you put a clip from c to f?// The voltage for bc would stay the same because it's current from the battery is not changed. But the current for the other two light bulbs would not flow because the wiring has changed, by avoiding other wires connecting to the other light bulbs. What's going on with this circuit? **
 * Complex Circuit

This can be a very confusing circuit, even for more advanced students. It turns out that electrical **//power//** through a bulb is the product of the voltage //across// the bulb and the current //running through// the bulb. For example, the electrical power through the first bulb could be calculated

P bc = V bc x I b

//**Check the power of each bulb by making these calculations. For the bulb between bc the power is about 0.7807. For the bulb between df the power is about 0.108. And for the bulb between eg the power is about 0.1768. **//

The **resistance** of a bulb is the ratio of the voltage across the bulb to the current through the bulb. For example, the electrical resistance of the first bulb could be calculated

R bc = V bc / Ib

For the bulb between bc the resistance is about 5.7027. For the bulb between df the resistance is about 4.8. And for the bulb between eg the resistance is about 2.6154. They are not the same. I am not really sure about the answer to why the numbers are different, but i will give the question a shot. Since bc had the highest voltage of all the bulbs, and a similar current to the other bulbs its resistance is greater. But for the df bulb and eg bulb the voltage are similar to each other but much less compared to Vbc. With these low voltages, and similar currents to all the other bulbs, when dividing the voltage by the current for the equation, df and eg currents have a smaller ratio to the voltage, as opposed to bc. But I still don't understand what the numbers from the equation are trying to tell me. **
