Question

The following apparatus is available in a laboratory
Cell: Adjustable from 0 to 1.5 volt
Resistor: 4 ohms and 12 ohms
Ammeters: A1 of range 0 to 3A: Least count 0.01 A2 of range 0 to 1A ; least count 0.05 A
Voltmeter: V1 of range 0 to 10V; Least count 0.5V ; V2 of range 0 to 5V; Least count 0.1 V
The best combination of voltmeter and ammeter for finding the equivalent resistance of the resistors in paraller would be
a) ammeter A1 voltmeter V1
b) ammeter A1 voltmeter V2
c) ammeter A2 voltmeter V1
d) ammeter A2 voltmeter V

Answer 1

options a is right ........

Answer 2

Answer:

Correct option is (a).

Step-by-step explanation:

Dear friends,

Millimeter A1 and voltmeter V1 gives maximum measuring range with lowest least count. So, the combination of these two is best for two resistances connected in parallel
