what is an advantage of series circuits?

a. adding more batteries will increase the current.
b. there is more than one path for charges to flow.
c. one bulb goes out, the other bulbs still shine.
d. light bulbs get dimmer as more bulbs are added.

Ans: A. Adding more batteries will increase the current.

A series circuit is one in which the electrical devices like resistors, batteries etc are connected in series i.e. in a row. In such circuits, there is only one path through which the charge or current can flow.

Based on Ohm's law, the current (I) flowing through a circuit is given by:

I = V/R

where V = voltage and R = resistance

For a series circuit, the total voltage is equal to the sum of individual voltages

V = V1+V2+V3+...

Therefore,

I = [V1+V2+V3+..]/R

Thus, adding more batteries will increase V and hence increase the current (I).

the formula would be mgso4
