Which of the following DOES NOT describe a current (the flow of electrical charge)?

• In a battery, your body, or other wet places, current is the flow of both positive and negative charges

• In metals, current is negative

• when currents flows in closed circuit, charges flow in a complete loop

• Short circuits do not produce high levels of currents
