Question 636314: If the voltage in an electric circuit is held constant, the current I is inversely proportional to the resistance R. If the current is 40 amperes when the resistance is 270 ohms, find the current when the resistance is 150 ohms. Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! If the voltage in an electric circuit is held constant, the current I is
inversely proportional to the resistance R.
If the current is 40 amperes when the resistance is 270 ohms,
find the current when the resistance is 150 ohms.
:
Ohm's law for finding the voltage; E = I*R
E = 40 * 270
E = 10,800 volts
:
Ohm's law for finding the current I = E/R
I =
I = 72 amps
