If the time constant of an RC circuit is large, is the response of the circuit slow or fast?

Question

If the time constant of an RC circuit is large, is the response of the circuit slow or fast?

Answer 1

slow

long time constant means long time. long time means (usually) slow.

Answer 2

slow

Answer 3

Slow, as it takes longer to charge the Capacitor. There are 5 times constants when charging a Cap, and in theory a Cap will never be fully charged. If 5 times constants are 20ms it will be slower than say a 5ms.
