There will be current flowing in E2 only when Vax and Vcd are not equal. E2 will produce current when Vax is too low due to decrease in length, and E2 will absorb current when Vax is too high due to increase in length. This is all due to the fundamental rule that the voltage drops across the paths in parallel should be the same!
