Answer 1

Answer:

5 amps

Explanation:

resistance in first parallel circuit - 2 ohm

second resistance - 3 ohms

resistance in second parallel circuit - 2 ohm

total resistance - 3 + 2 + 2 = 7 ohms

we know I = V/R

I = 35v/ 7 ohms

I = 5 amps

Answer 2

Answer: 5 A

Explanation:1/Rp= 1/R1+1/R2

                 ⇒ 1/Rp= 1/4=1/4= 2/4= 1/2

                   ∴ Rp=2Ω - (i)...

                  In series,

                                   R= 3Ω - (ii)...

                  Now, we have,

                                             ∵ 1/Rp= 1/R1+1/R2+1/R3

                                             ∴ 1/Rp= 1/6+1/6+1/6

                                                ⇒1/Rp=3/6=1/2

                                    Hence, Rp=2Ω - (iii)...

                     Adding (i), (ii) and (iii), total resistance of the circuit is,

                                 2Ω+3Ω+2Ω=7Ω           (∵Rs= R1+R2+R3)

                       We know that I = V/R

                                           ∴ I = 35v/7Ω = 5A

                      Hope this helps.....
