QUESTION:
Eight identical lights are connected in series across a 110-V line.
(a) What is the voltage across each bulb?
(b) If the current is 0.50 A, what is the resistance of each bulb, and what is the power dissipated in each?
ANSWER:Step 1 of 4
(a) Given eight lights are connected in series so the equivalent resistance is,
\(R_{e q}=8 R\)
The current through the lights is given by,
\(\begin{array}{l}
I=\frac{V_{t o t}}{R_{e q}}\\
I=\frac{V_{t o t}}{8 R} \ldots \ldots \ldots . . .(1)
\end{array}\)
