1. "shaping" the lines of force of this field in certain paths — придавая силовым линиям определенные направления
2. whether or not these electrons actually reach the plate, however, is determined by the plate-to-cathode voltage — однако попадание или непопадание электронов на анод определяется анодным напряжением
