True or False A moving charge entering a magnetic field parallel to the field will move in a straight line. A man whose resistance is 10,000 Ω has 120 volt potential difference across his body. This would cause a fatal shock. Adding resistors to a parallel circuit decreases the equivalent resistance. The resistance of a resistor increases with decreased temperature The terminal voltage (V) of a battery is always less than its EMF (ξ). The electric field E is a scalar but the electric potential V is a vector.
