Question

(Resistors in Series and Parallel) In which 120-V light bulb does the filament have greater resistance: a 60-W bulb or a 120-W bulb? If the two bulbs are connected to 120-V line in series, through which bulb will there be the greater voltage drop? What if they are connected in parallel? Explain your reasoning.

Answer 1

The 120-W bulb has a greater resistance and will have a greater voltage drop.

What is power?

Electrical power is the rate at which work is done in a circuit. It is obtained by; P = V^2/R

For the  60-W bulb;

R = P/V^2 = 60-W/(120)^2

R = 0.0042 ohm

For the 120-W bulb;

R =  P/V^2 =  120-W /(120)^2

R = 0.0083 ohm

Hence, we can see that when we compare the two bulbs, the 120-W bulb has a greater resistance and will have a greater voltage drop.
