The voltmeter is connected across the two ends of a conductor to measure the potential difference across the two terminals of the conductor. The voltmeter is connected across the two poles of a battery...
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 electric current is a flow of electric charges through a conducting material, The electric current flows from the positive pole to the negative pole outside the source & it is called the conventional...
The electric resistance (The resistor) The electric current faces an obstruction (resistance) when it passes through a conductor which affects its intensity, The electric resistance is the opposition that the electric current faces during...
