\(V= RI\)
\(R=\frac{V}{I}\)
\(\frac{5}{200}\times100\%+\frac{0.2}{20}\times100\%\)
\(3.5\%\)
\(\text{The Correct option is (A):}\) \(3.5 \%\)
Consider the circuit shown. Galvanometer resistance is \(10\) \(Ω\) and current through galvanometer is \(3\) \(mA\). Find the resistance of shunt.
Sample | Van't Haff Factor |
---|---|
Sample - 1 (0.1 M) | \(i_1\) |
Sample - 2 (0.01 M) | \(i_2\) |
Sample - 3 (0.001 M) | \(i_2\) |
Resistance is the measure of opposition applied by any object to the flow of electric current. A resistor is an electronic constituent that is used in the circuit with the purpose of offering that specific amount of resistance.
R=V/I
In this case,
v = Voltage across its ends
I = Current flowing through it
All materials resist current flow to some degree. They fall into one of two broad categories:
Resistance measurements are normally taken to indicate the condition of a component or a circuit.
