Web27 jul. 2006 · An electric field (created by the potential difference between cathode and anode) is required in order for electrons to leave the cathode and create a current. The electron flow does not affect the electric field between the anode and cathode. That field depends only on the potential difference that is applied. AM. Jul 27, 2006. WebThe test charge (a unit charge that is used to test the effect of the source charge) is assumed to be positive. So, the source charge, which is the charge from which the electric fields are generated, pushes the test charge outwards. And so, the electric field lines are radially outwards. Totally sure now. Hope that helped.
