Hi, I need help with an electricity question where it requires for me to see the circuit diagram and figure out: volage drop across the resistor (V), current flowing through the resistor (I), the resistance constant (R).(adsbygoogle = window.adsbygoogle || []).push({});

Here is the link to the diagram that I've scanned:

Basically, I need to figure out all the V, I and R for each resistor,

so basically I need to figure out everything, which are...

R1, R2, R3, Rt (total), I1, I2, I3, It (total), V1, V2, V3 and Vt (total)

I thought I could find Rt by using the equation:

Rt = R1 + R2 + R3 or 1/Rt = 1/R1 + 1/R2 + 1/R3, but none of those work. I think the only way to start this question is to figure out Rt first.

By the way, the answers are:

It = 12A

Rt = 11 ohms

Vt = 132V

I1 = 12A

R1 = 7.67 ohms

V1 = 92V

I2 = 4A

R2 = 10 ohms

V2 = 40V

I3 = 8A

R3 = 5 ohms

V3 = 40V

I greatly appreciate your help. Thanks in advance!
