Need help with those questions please
An 8 V battery connected to a wire generates a 5 A current. If
the radius of the wire is changed by a factor of 0.5 without
changing the battery, what would be the new current flowing through
the wire?
A resistor is connected to a battery with negligible internal
resistance. If you replace the resistor with one that has 6.4 times
the resistance of the first one, by what factor does the power
dissipated in the circuit change?
Replacing a wire resistor with another of the same material and
length but with 4 times the diameter will have the effect of
changing the resistance by what factor?
