Here's your symbols.
Hope helped

Answer 2

The symbols for the following: (a) a bulb, (b) an electric cell, (c) a switch (d) a battery of electric cells is attached below.

Explanation:

Three conditions need to be fulfilled for electric current to flow:

• A source of electric current (cell and battery).
• Unbroken path for the flow of charge.
• A metal wire for conducting an electric current.

Components of the electric circuit:

Electric bulb :

• An electric bulb consists of a thin wire called a filament, which glows and produces heat when an electric current passes through heat.

Cell  :

• A cell is a source of electric current. It has 2 terminals positive terminal and a negative terminal.
• The positive end (+) of the cell is connected to the negative end (-) of the second cell, and so on.

On-off switch:

• An electric circuit has a switch. A switch is a simple device that helps us to close or open the circuit.
• The electric circuit is complete when the switch is in the ‘ON’ position, and the current can flow through the circuit.
• When the switch is in the ‘OFF’ position, the circuit is incomplete, no current flows and the appliance does not work.

Battery :

• The combination of 2 or more cells is known as a battery.
• A battery can be made by connecting cells in two ways: series or parallel.
