Answer:
emf = 0.437 V
Explanation:
given: R= 6×10³Ω, t=0.15 s, C = 20 × 10 ⁻⁶ F, I= 0.62 × 10 ⁻³ A
Solution:
Using formula I = I₀ × [tex]10^{-t}[/tex]/RC
⇒ I₀ = I RC /[tex]10^{-t}[/tex]
I₀ = 0.62 × 10 ⁻³ A × 5×10³Ω × 20 × 10 ⁻⁶ F / [tex]10^{0.15}[/tex]
I₀ = 0.000062 /0.707
I₀ = 8.758 × 10⁻⁵ A
emf = I₀ × R
emf = 8.758 × 10⁻⁵ A × 5×10³Ω
emf = 0.437 V
