Question

Can someone please help with this question

Answer 1

Answer:

i⟩ Re = 8.33Ω, I = 4.8A

Explanation:

i⟩ Re = 1

1/10 + 1/50

= 1

6/50

= 1

3/25

= 25/3

= 8.33 Ω

V = IR

40 = 8.33 I

I = 40/8.33

= 4.8 A

ii⟩ Across R1

V = IR

V = 4.8 × 10

V = 48v

∆V = (V - e.m.f) = 8v

Across R2

Same process

Across R3 add take the R2's voltage.
