1) The potential difference or voltage between points 1 and 2, if the electric charge moves from point 1 (φ1 = 110 V) to point 2 (φ2 = -110 V).
U = φ1 – φ2 = 110 – (- 110) = 110 + 110 = 220 V.
2) Potential difference if the electric charge moves from point 2 to point 1.
U = φ2 – φ1 = -110 – 110 = -220 V.
Answer: 1) U = 220 V, 2) U = -220 V.
