Analog Ammeters

Analog ammeters are metered instruments that measure current flow in amperes. They display current levels on a dial, usually with a moving pointer or needle. Analog ammeters provide information about current draw and current continuity in order to help users troubleshoot erratic loads and trends. They have both positive and negative leads and feature extremely low internal resistance. Ammeters are connected in series with a circuit (and never parallel) so that current flow passes through the meter. High current flow may indicate a short circuit, unintentional ground, or defective component. Low current flow may indicate high resistance or poor current flow within the circuit.
