Answer:
sorry but which class your talking 'bout
Answer:
Resistance of the circuit is 820 Ω
Explanation:
Given:
Two galvanometer resistance are given along with its voltages.
Let the resistance is "R" and the values of voltages be 'V' and 'V1' along with 'G' and 'G1'.
⇒ 
⇒ 
Concept to be used:
Conversion of galvanometer into voltmeter.
Let
be the resistance of the galvanometer and
the maximum deflection in the galvanometer.
To measure maximum voltage resistance
is connected in series .
So,
⇒ 
We have to find the value of
we know that in series circuit current are same.
For
For 
⇒
equation (i) ⇒
equation (ii)
Equating both the above equations:
⇒
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ Plugging the values.
⇒ 
⇒ 
⇒ 
⇒
The coil resistance of the circuit is 820 Ω .
