Question

In this case when finding the total current flowing from the battery, you need to consider the overall, or equivalent, resistance of the circuit. Suppose the voltage source provides a potential difference (voltage difference) of 7.60 V. What is the total current flowing from the battery?

These two resistors are in series. First, stop and trace the current flowing from the battery through the complete circuit. Now, what is the current flowing through resistor R1?

What is the current flowing through resistor R2?

Explanation / Answer

Here ,

as resistances are connected in series

Req = R1 + R2

Req = 13.4 + 27.4

Req = 40.8 Ohm

the equivalent resistance of the two combined resistance is 40.8 Ohm

---------------------------------------------

Using Ohm's law

I = 7.60/40.8

I = 0.186 A

total current is 0.186 A

-------------------------------------------------------------------
the current in both the resistors will be same

current through R1 is 0.186 A

current in r2 is 0.186 A
