Question
The amount of current flowing into an electrical circuit varies inversely as the resistance in the circuit. When the resistance of a particular circuit is 5 ohms, the current is 42 amperes. what is the current when the resistance is 4 ohms?

I = E/R
42 = E/5 so E = 210 volts
at R=5 ohms,
I = 210/4 = 52.5 amps
42 = E/5 so E = 210 volts
at R=5 ohms,
I = 210/4 = 52.5 amps
