Question
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?
The figure shows two resistors in series. R1=19.8 ? and R2=31.2 ?. res_2series.gif 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
if resistances are in series
a)
R=R1+R2 =19.8+31.2
R=50 ohms
b)
I=V/R =9.28/50
I=0.1856 A
c)
I1 =0.1856 A
I2=0.1856
