Find the p. d across the filament lamp when the current flowing through it is 5A and the resistance is 20 Ohms using Ohm's law equation.

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.
