In a series circuit, the voltage across the circuit is always equal to
a. the voltage across one of the bulbs.
b. the sum of the voltages across each bulb.
c. half the sum of the voltages across each bulb.
d. two times the sum of the voltages across each bulb.

b. the sum of the voltages across each bulb.

This is unlike parallel circuit where the voltage across the circuit is the same as across each resistor or bulb.

Answer:

b. the sum of the voltages across each bulb.

Explanation:

As we know that the total voltage across the given series circuit will give some current to the circuit

The current will remain the same in the circuit in all the resistors.

So here we will have voltage across each resistor given by

[tex]V_1 = i R_1[/tex]

[tex]V_2 = i R_2[/tex]

[tex]V_3 = i R_3[/tex]

and so on

so here for total voltage across all the resistors we can say

[tex]V = V_1 + V_2 + V_3 + ........[/tex]

so correct answer will be

b. the sum of the voltages across each bulb.
