Write the symbols used for switch on and off position.

Write the conventional symbol of the following component used in electric circuit diagram-

A wire joint

A student uses the resistance of a known resistor ($1 \Omega$ ) to calibrate a voltmeter and an ammeter using the circuits shown below. The student measures the ratio of the voltage to current to be $1\times {10}^3\Omega$ in circuit
(a) and $0.999\Omega$ in circuit (b). From these measurements, the resistance (in $\Omega$ ) of the voltmeter and ammeter are found to be close to

In the given circuit diagram, identify the objects marked as $1, 2, 3$.
