The current in an electrical conductor varies inversely as the resistance of the conductor. What is the current when the resistance is 42 ohms, if the current is 4 amperes when the resistance is 168 ohms?
Question
Answer:
Current1 / currebt2= Resistance2 / resistance1x/4A=168 Ohm/ 42 Ohm
x=4*168/42= 16 A
