RC ChargingMediumQuestion 31546
Question
In an RC charging circuit with time constant τ = RC, charge after time t is:
- AQ₀(1−e^(−t/τ))Correct
- BQ₀e^(−t/τ)
- CQ₀t/τ
- DQ₀(1+e^(−t/τ))
Correct answer
Q₀(1−e^(−t/τ))
Explanation
During charging, Q(t) = Q₀(1 − e^{−t/RC}) where Q₀ = CE is the final charge.
