FREE Expert Solution

The bulbs act as resistors.

Assuming that each bulb has a resistance of R, we can get the equivalent resistance for the different cases.

Remember,

Equivalent resistance for resistors in parallel:

1Req=1R1+1R2+...+1Rn

Equivalent resistance for resistors in series:

Req=R1+R2+...+Rn
