Question
you place tow resistors in parrallel and use to batteries with a total voltabe of 3v. you read the color code of the first resistor to be red red red and for the second resistor you read brown black green.
a) calculate the equivalent resistance. show your solution to get credit.
b) calculate the current in circuit, current ending the first resistor, current entering the second resistor. show your solution to get credit.
c) calculate the voltage across each resistor. show your solution to get credit.
Explanation / Answer
here,
voltage , V = 3 V
R1 = 2.2 kohm
R2 = 1000 kohm
a)
the equivalent resistance be Req
1/Req = 1/R1 + 1/R2
Req = 2.195 kohm
the equivalent resistance is 2.195 kohm
b)
current ending the first resistor , I1 = V/R1
I1 = 1.36 * 10^-3 A
current entering the second resistor , I2 = V/R2
I2 = 3 * 10^-6 A
c)
as the resistance are in parallel
the voltage drop is same
the voltage drop is 3 V
