SOLUTION: The current I varies directly as the electromotive force E and inversely as the resistance R. If in a system a current of 20 amperes flows through a resistance of 20 ohms with an e

Question 1189965: The current I varies directly as the electromotive force E and inversely as the resistance R. If in a system a current of 20 amperes flows through a resistance of 20 ohms with an electromotive force of 100 volts, find the current that 150 volts will send through the system.

If in a system a current of 20 amperes flows through a resistance of 20 ohms with an electromotive force of 100 volts
--------------
E = I*R
20*20 = 400 volts, not 100.
==================
150/20 = 7.5 amperes
