Question

If the voltage V in an electrical circuit is held constant, the current 1 is inversely proportional to the resistance R. If the current is 280 milliamperes when the resistance is 3 ohms, find the current when the resistance is 12 ohmz.

Answer 1

the current =0.07 amps = 70 milliamps when resistance = 12 ohms

C= V/R Current = volts over ohms

.28 = V/3

V = 3(.28) = .84 volts

C= .84/12 = 0.07 amps = 70 milliamperes when R=12 ohms
