to increase the resistance
1) make the wire really really long
2) make the diameter very large
3) put the wire in a magnetic field that opposes the current flow
to increase the current flow
1) make the wire short
2) make the diameter small
3) place the wire in a magnetic field that assists the current flow

resistance decrease
make copper wire thinner, longer, or colder.
you can do the opposite of all those things to make the current go up or increase the voltage on the wire.

the very first step taken by you is misguided 40 V of battery at the on the spot are not appearing in the approach seriess blend of R1 and R3. besides the undeniable fact that it truly is about the series blend of R1, R2 and R3. so which think ofyou've got written 40/[240+R2+120] = present day passing by each of them. allow this present day be i. it truly is on condition that the voltage in the approach R1 = 240 ohm is 24 volts. So employing Ohm's regulation we've 240*i = 24 or i, the present contained in the circuit is 24/240 = 0.a million A. So 40/[360+R2] = 0.a million or 40 = 36 + R2 or R2 = 4 ohm

Thicker guage wire or longer length will both have more resistance - or do both, a longer length of a larger guage
