how to find the least count of voltmeter and ammeter ?
what is the
1.range of the given ammeter a nd voltmeter???
2.least count of ammeter and voltmeter???
3.zero error in ammeter and voltmeter???
4.zero correction for ammeter and voltmeter???plzz help me out experts i got to give my gernals wit these questins tmr......pls help me out smeone......
While experimentally verifying Ohm's Law a student observed that the pointer of the voltmeter coincide with 15th division when the voltmeter has a least count of 0.05V. Find the observed reading of voltmeter.
What is Least count and how to calculate it
describe any three ways in which individuals with a particular trait may increase in population?
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 V2

Whila performing the experiment "to study the dependence of current flowing through a resistor on the potential difference across its ends" if a student keeps the circuit 'ON' for a long time to measure the current and voltage source then what will happen.
While performing the experiment of Ohms law, a student has plotted the following graph. The resistance of the conductor will be :
what is zero error and least count and how are they calculated in ammeter and voltmeter?
A voltmeter had graduations 0, 0.5, 1.0 etc. A student noticed that pointer of voltmeter was indicating the third graduation mark after 0 mark even when the circuit was open, The space between 2.0 and 2.5 was divided into 10 equal divisions. Find the zero error.
how to find resistance using the graph?
dear meitnation can u please explain it mathematically using the ohms law. also show the graph.?
In the above circuit connection why switch is connected towards the negative terminal?
What is Resistance?
What is intrapolation and extrapolation in a graph ?
How to check for zero error and least count??
who is ohm
how did he got idea about this relation
was it lt like newtons
in an experiment to study dependency of current on the potential difference across a given resistor four students p,q,r,s kept the plug key in the circuit closed for time t1 and then open for time t2.......
t1 for p=15 sec
t2 for p=45sec
t1 for q=45 sec
t2 for q=15sec
t1 for r=60 sec
t2 for r=30sec
t1 for s= 45sec
t2 for s= 30sec
What do u mean by eliminator???
what is meant by rheostat???
correct!i need "procedure" of the experiment in written form!!!
how to find the zero error
In the above circuit connection voltmeter should be connected in parrallel. please check it and inform it to me.
so.......nicely..explained..i like dis.....thnx to meritnation....
hoe to measure the least count???/.......during our practical we haveto count least count of ammeter and voltmetter....pls tell how to do that manually
HEY CBSE BOARD GIVERS..... IN SC. EXAM DS TIME, 16 MARKS MCQ WAS BASED ON X'S PRACTICALS....???
Plzzzzzzzzzzz. answer........ this is very urgent........
The current varies linearly with the potential difference across a resistor. The slope of this variation will give :
(a) resistance (b) conductance (c) inductance (d) capacitance
sir this question is not from this chapter but still i want help
WHAT IS VECTOR
In this circuit results why the resistance is not constant..... as it will fail the ohms experiment....
How to check for zero error and least count...????
how to find the lest count of the ammeter and voltmeter?
why don't we connect resistors to the circuit?
how to find the least count
please answer me faast..........because tomorrow is my practical xam....
how to find the least count of ammeter and voltmeter?????
how can we convet ampere into miliammpere?
What is DC voltage
We have to keep the resistance same or we have to vary resistance?
any one out der whose exams are on march 5th??? cbse 10th?
