Answer 1

1. The resistor is located at point D.

A resistor is an element of a circuit that opposes to the flow of current through it: the value of its resistance (R) tells how much the resistor opposes to the flow of current, and the resistance is related to the voltage in the circuit (V) and the current (I) by the Ohm's law:

$V=IR$

Resistance is measured in Ohm ($\Omega$), and a resistor is usually represented with a zig-zag line as the one at point D.

2. The switch is located at point B.

A switch is an element of the circuit that can be switched on and off, opening and closing the circuit, therefore allowing or not the flow of current through it. When the switch is open, no current flows; when it is closed, the current can flow through the circuit.

The symbol of a switch is represented at point B.

Answer 2

1). The resistor is located at the point D in the given diagram.

2). The switch is located at the point B in the given diagram.

Explanation:

A resistor in a circuit is a component that opposes the flow of current through the circuit. The resistance is the measurement of the hindrance produced by the conductor in the path of the current flowing through it.

A switch on the other hand is another important part of a complete circuit. A switch is a component which is used to switch on an off the current flowing through the circuit.

The other important components of a complete circuit are the battery, connecting wires etc. The battery is the source of power that runs the complete circuit and connecting wires are the medium that allow the flow of current from one end of the circuit to the other end.

The symbols of the various components are shown in the figure attached below:

Therefore,

Part (1):

The resistor is located at the point D in the given diagram.

Part 2):

The switch is located at the point B in the given diagram
