## Homework Statement

I made this problem on my own.

resistors are

10 ohms

30 ohms

15 ohms

they are in parallel connections between A and B points

Voltage across A and B = 12 volts

calculate R

_{total}

## Homework Equations

1/ R = 1/ R

_{1}´+ 1/R

_{2}+ 1/R

_{3}

## The Attempt at a Solution

1/R = 1/10 +1/30 + 1/15

1/R = 6/30 = 1/5

R/1 = 30/6 = 5/1

R= 5 ohms

If the inverse of R = 6/30

I guess then R itself should be inverse of (6/30) = 30/6

I think I got the same result with the laborious method.

1/R = 6/30 ]]]] * R

1= 6R/30 ]]]] * 30

30= 6R ]]]] / 6

30/6 = R

R= 5 ohms
