Question

You are given a 9V battery and two resistors. The first resistor has a value of R1 =73 capital omega and the second has a value of R2 =53 capital omega . If the two resistors are placed in parallel and connected to the battery... What is the equivalent resistance of the circuit? capital omega What is the value of the voltage across resistor R1? What is the value of the voltage across resistor R2? What is the value of the current through the resistor R1? What is the value of the current through the resistor R2? What is the value of the voltage across the battery? What is the value of the current through the battery?

Explanation / Answer

a)

Req =R1R2/(R1+R2)

Req =30.71 ohms

b)

VR1 =9V

c)

VR2 =9V

d)

IR1 =VR1/R1 =0.1233 A

e)

IR2 =VR2/R2 =0.1698 A

f)

V=9V

f)

I=V/R =9/30.71=0.2931 A
