Question

Two factors that reduce efficiency of a pulley system .How can each factor be controlled.

Answer 1

Answer:

According to Ohms Law (I=E/R or Amps=Volts/Ohms) if the voltage in the circuit remains constant and the resistance is increased, the current should decrease. Try adding resistance to the circuit to lower the current output.
