Answer:

a). 3Ω

b). 5Ω = 2.4 A , 10Ω = 1.2 A , 20Ω = 0.6 A

c). 4.2 A

Explanation:

Given-

r1= 5Ω ,r2 = 10Ω , r3 = 20Ω

V = 12 ( battery

a). Total Resistance -

In Above Picture Resistance Connected In Parallel

So, Total Resistance is -

$\frac{1}{p} \: = \: \: \frac{1}{5} \: + \frac{1}{10} \: + \frac{1}{20}$

1/p = 1/3

So,

$\bold{\boxed{P= 3}}$

Resistance In Parallel= 3Ω

b). Current Through Each Resistor -

1. Current Through 5Ω Resistor

R = 5Ω

V = 12v

I¹ = ?

Using Ohm's Law

i•e,

V= IR

So,

I = V/R

I = 12/5

I¹ = 2.4 A {Ampere)

2. Current Through 10Ω Resistor -

R = 10Ω

V = 12V

I² = ?

By Ohms Law

V = IR

So,

I = V/R

I = 12/10

I² = 1.2 A

3. Current Through 20Ω Resistor -

R = 20Ω

V =12 v

I³ = ?

I = V/R

I = 12/20

I³ = 0.6 A

So,

I¹= 2.4 A

I²= 1.2 A

I³= 0.6 A

c). Total Current -

We Have,

I¹ = 2.4 A , I² = 1.2 A , I³ = 0.6 A

So Total Current Is

I = I¹ + I² + I³

I = 2.4 + 1.2 + 0.6

I = 4.2 A
