Question
Consider the circuit shown in the picture and composed of a VB= 12 Volt battery and resistors R1= 5 ?, R2= 6 ?, R3= 2 ?, R4= 1 ?, and R5= 6 ?.
1. What is the equivalent resistance of
R3 and R4?
2. What is the equivalent resistance of
R2, R3and R4?
3. What is the equivalent resistance of the entire circuit?
4. How much current does the battery provide to the circuit?
5. How much power does the battery provide to the circuit?
6.What is the voltage across R1?
7. What is the voltage across R2?
8. What is the current through R3?
Explanation / Answer
R3 and R4
Requivalent=R3+R4=3ohm
R2, R3and R4
RR3&R4|R2= Requivalent +R2
= 2ohm
=9ohm+5ohm+6ohm
=13ohm
I=V/ RCircuit
I=0.923A
=11.077J
=0.923*5
=4.615
V=0.307*6
=1.844V
I=0.923*2/3
=0.0.615A
