29-30. 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?

A. 10 amperes

B. 20 amperes

C. 30 amperes

D. 40 amperes​
