AC dynamo generates an alternating current which its intensity increases from zero to maximum value then drops to zero again in the first half cycle, next to that, the current direction is reversed and...
Analog measuring instruments depend on the torque that is generated in a moving coil carrying current in a magnetic field, They depend on a pointer to give the value of the quantity, such as...
The electrical measurement devices are divided into types such as analog instruments and digital instruments, Moving coil galvanometer (sensitive galvanometer) is a device used to detect very weak current in the electric circuits, It...
Electric resistances can be connected in the electric circuit using two methods which are series connection, parallel connection, Home appliances are connected in parallel, Thus every device can work individually on the potential difference...
