Answer 1

Explanation:

the resistors are 5,10,and 30

using v=IR

V= 6

value of current in each resistance is

1) 6= 5×i

I =6/5

I = 1.2

2) 6 = 10 × I

I = 10/6

I = 1.67

3)6=30×i

I=30/6

I=5

potential difference across each resistance

we first find total current in the circuit by using

1/R=1/R' +1/R" +1/R"'

1/R =1/5+1/10+1/30

1/R=1/3

R=3

by using v=IR

6=3×i

I=2

1) v=5×2

2)v=10×2

3)v=30×2

total current in d circuit is I=2

so also, effective resistance I have solve it above which=R=3
