    While on a field trip focused on dance observation, students are encouraged to record key details like the name of the dance, the performers’ names and what steps, movements and expressions were observed. They should also note the musical instruments used, costumes worn and any unique traditions or stories shared by the dancers. This documentation supports a deeper reflection on the experience and helps in comparing and understanding different dance forms in later discussions or assignments.

  3. Total resistance in the circuit = 100Ω + 50Ω = 150Ω Current through the galvanometer at full scale deflection: I = V/R = 1.5/150 = 0.01A = 10, 000µA Galvanometer has 20 divisions, so: Figure of merit = 10, 000µA/20 = 500 μA/division Answer: (C) 500.

    Total resistance in the circuit = 100Ω + 50Ω = 150Ω

    Current through the galvanometer at full scale deflection:
    I = V/R = 1.5/150 = 0.01A = 10, 000µA
    Galvanometer has 20 divisions, so:
    Figure of merit = 10, 000µA/20 = 500 μA/division
    Answer: (C) 500.

  4. Let the shunt resistance be Rs and galvanometer resistance be Rg = 3663Ω ​Given: only 1/34 of total current I passes through the galvanometer. Using current division rule: Ig/Is = Rs/Rg ' Where Ig/I = 1/34' ⇒ Is/I = 33/34 So: 1/33 = Rs/3663 ⇒ Rs = 3663/33 = 111 Ω ≈100Ω Answer: (A) 100 Ω.

    Let the shunt resistance be
    Rs and galvanometer resistance be
    Rg = 3663Ω

    ​Given: only 1/34 of total current I passes through the galvanometer.
    Using current division rule:
    Ig/Is = Rs/Rg ‘ Where Ig/I = 1/34’ ⇒ Is/I = 33/34
    So:
    1/33 = Rs/3663 ⇒ Rs = 3663/33 = 111 Ω ≈100Ω

    Answer: (A) 100 Ω.

  5. To convert the galvanometer into an ammeter reading up to 10 A, a small shunt resistance must be added in parallel, allowing most current to bypass the galvanometer. The galvanometer allows only 0.1 mA. Using the formula Rs = Ig.Rg/I-Ig, we get Rs ≈ 0.01Ω. Correct answer: (B) 0.01 Ω in parallel. ForRead more
