Bridge circuits

measuring instrument in electricity

circuit arrangement of four diodes

An H-bridge is an electronic circuit that switches the polarity of a voltage applied to a load. These circuits are often used in robotics and other applications to allow DC motors to run forwards or backwards. The name is derived from its common schematic diagram representation, with four switching elements configured as the branches of a letter "H" and the load connected as the cross-bar.

measuring instrument invented by William Thomson, 1st Baron Kelvin used to measure an unknown electrical resistance below 1 Ω
