Hi I just need to know if these statements are true or false and why!! 1. Electric field lines always point from higher to lower potential, meaning that a positive test charge would then seem to "fall" in the correct direction. 2. A student measures the potential between parallel plates A and B, and the meter reading is +30 V. The student concludes that there is a charge on plate B, but none on plate A. 3. If a capacitor...
