Question

Study the circuit shown and answer the following questions:
a) What is the function of X in the circuit?
b) What would happen to the current drawn from the cell if
X and Y interchanged?
c) Name and state the function of Z in the circuit.
d) Why should we prefer a higher value of the resistor R while verifying Ohm’s law in​

Answer 1

Explanation:

Clearly the ammeter and resistor are connected end to end, thus they are in series. Also resistor and rheostat are in series, sine they are also joined end to end. So, the ammeter and rheostat are in series.
