Question

List in a tubular form three differences between a voltmeter and an ammeter.

Answer 1

AMMETER....[{∆}]

• IT IS USE TO MEASURE CURRENT IN GIVEN CIRCUIT.
• ALWAYS CONNECT WITH SERIES WITH THE RESULTANT AND WITH INDIVIDUAL RESISTORS
• HAVE LOW RESISTANCE VALUE SO THAT CURRENT CAN EASILY PASS THROUGH IT.
• IT SYMBOLICALLY REPRESENTED BY LETTER "A" IN THE CIRCUIT DIAGRAM.

VOLTMETER.....[{¶}]

• IT IS USE TO MEASURE POTENTIAL DROP ACROSS THE RESISTANCE.
• ALWAYS CONNECT IN PARALLEL WITH RESISTANCE.
• HAVE VERY HIGH VALUE OF THE RESISTANCE SO THAT THE CURRENT CAN EASILY GO THROUGH THE RESISTANCE AND GIVE A PROPER POTENTIAL DROP ACROSS IT.
• IT IS SYMBOLICALLY REPRESENTED BY LETTER "V" IN CIRCUIT DIAGRAM
