Find the current through the resistor and the capacitor for the current shown in figure The switch is closed at t = O and initial change in the capacitor is zero.

I(t) = 5(1 - e⁵⁰⁰⁰ᵗ) A

I(t) = 10e⁵⁰⁰⁰ᵗ A.

I(t) = 10(1 - e⁵⁰⁰⁰ᵗ) A

I(t) = 5e⁵⁰⁰⁰ᵗ A.

I(t) = 5(1 - e⁵⁰⁰⁰ᵗ) A

I(t) = 10e⁵⁰⁰⁰ᵗ A.

I(t) = 10(1 - e⁵⁰⁰⁰ᵗ) A

I(t) = 5e⁵⁰⁰⁰ᵗ A.
