Question

Ans of 29 b pls post it as fast as possible

Answer 1

Given ;

3 parallel resistors of ;

• R1 = 30 Ω
• R2 = 5 Ω
• R3 = 10 Ω

Total Voltage = 3 + 3 = 6V

Using ohm's law

a)

I through R1 =>

• V = IR
• 6 = I×30
• I1 = 1/5 A

I through R2 =>

• V = IR
• 6 = I×5
• I2 = 6/5

I through R3 =>

• V = IR
• 6 = I×10
• I3 = 3/5

b)

Total I through all the resistors ;

= I1 + I2 + I3

• 1/5 + 6/5 + 3/5
• 10/5
• 2 A

c)Total resistance ; by ohm's law;

• V = IR
• 6 = 2×R
• R = 3Ω
