The time constant τ = R × C is the time to charge to about 63% of the supply voltage. After 5τ the capacitor is regarded as fully charged (>99%).

Mene ne bambanci a tsakanin canzawa da fitarwa?
Charging rises toward the supply as V(1 − e^(−t/τ)); discharging falls from the starting voltage as V·e^(−t/τ). Both reach ~99% of the change after 5 time constants.
Da yawa ne zafi da capacitor ke da shi?
The charge is Q = C × V in coulombs. A 1,000 µF capacitor at 5 V holds 0.001 × 5 = 0.005 C. Larger capacitance or higher voltage both store more charge, in direct proportion.
Da yawa har zuwa capacitor ne a charged gaba ɗaya?
Practically, after five time constants (5τ = 5RC) it is within about 1% of the supply and treated as full. With a 1 kΩ resistor and 1,000 µF capacitor τ is 1 s, so it is essentially charged after roughly 5 seconds.
Da gaske?
Charging reaches about 63% after 1τ, 86% after 2τ, 95% after 3τ, 98% after 4τ and 99% after 5τ. Discharging follows the mirror image: 37%, 14%, 5%, 2% and 1% remaining at the same points.
Me yasa ka ƙara wani jerin resistor a duk?
The resistor sets the charging speed. Without it the current spike at switch-on is limited only by stray resistance and can be huge; the resistor makes the timing predictable, which is exactly what RC timers, filters and debounce circuits rely on.
