A filter circuit is activated when the current reaches 5 amperes. If a charge is fed to the circuit starting at 1 ampere and is steadily increased by 50% of the current value every 10 seconds, how long will it be until the filter activates?

Respuesta :

final value = 5 amperes initial value = 1 ampere rate = 1 + 0.5 = 1.5 every 10 seconds set up a growth equaiton
solve t
