[Answer] it takes ______(how many) time constants for a capacitor to fully charge

Answer: five




Most relevant text from all around the web:


it takes ______(how many) time constants for a capacitor to fully charge Ad Find Price Availability & Datasheets From The Top Distributors Worldwide. Find electronic parts · Instant stock and pricing Most stock chargers these days can fully charge a Galaxy S3 in 2-3 hours . So see if your charger can fully charge your S3 in that time. ... The time constant of a resistor-capacitor series combination is defined as the time it takes for the capacitor to deplete 36.8 % (for a discharging circuit) of its charge or the time it takes to reach 63.2% (for a charging circuit) of its maximum charge capacity given that it has no initial charge. Electronics All-in-One For Dummies. Knowing exactly how much time it takes to charge a capacitor is one of the keys to using capacitors correctly in your electronic circuits and you can get that information by calculating the RC time constant. When you put a voltage across a capacitor it takes a bit of time for the capacitor to fully charge. Therefore it is safe to say that the time it takes for a capacitor to charge up to the supply voltage is 5 time constants . To calculate the time constant of a capacitor the formula is τ=RC. This value yields the time (in seconds) that it takes a capacitor to charge to 63% of the voltage that is charging it up. With a constant DC voltage applied to an RC combination it takes 5 time constants to charge the capacitor to 99% of applied voltage. This can be considered near full charging of capacitor. it takes _____(how many) time constants for a capacitor to fully charge five when a capacit...
