Description : State the concept of internal voltage drop.

Last Answer : Concept of internal voltage drop: Every practical source offers some opposition to the current due to its internal parts or components. e.g. a 12V battery has electrodes made up of conducting ... internal voltage drop, the terminal voltage of practical voltage source is always less than its emf. 

Description : What is internal voltage drop and terminal voltage?

Last Answer : It is not permissible to just connect the positive terminal to the negative terminal of a cell with a copper wire. It will overheat and get damaged. This happens because the electromotive force (emf) ... than the nominal voltage (emf) of the cell and this lower voltage is called terminal voltage.

Description : To determine the polarity of the voltage drop across a resistor, it is necessary to know?

Last Answer : To determine the polarity of the voltage drop across a resistor, it is necessary to know direction of current through the resistor.

Last Answer : In order that current should flow without causing excessive heating or voltage drop, the relay contacts should have low contact resistance, be clean and smooth, be of sufficient size and proper shape.

Description : In alternator where the voltage drop occurs?

Last Answer : In alternator voltage drop occurs in armature resistance, leakage reactance, and armature reactance.
