Question

The figure shows two resistors in series. R1=19.8 ? and R2=31.2 ?.

What is the equivalent resistance of the two combined resistors?

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 9.28 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

R eq = R1 + R2 = 19.8 + 31.2 = 51 ohms

We need to consider the equivalent resistance   

I = V/ R = 9.28 / 51 = 0.182 Amperes

In series connection Current flowing through both R1 and R2 are equal and is equal to the current in the circuit

SO current in R1 = Current in R2 = 0.182 Amperes
