Question

Draw circuit symbols for (a) fixed resistance (b) variable resistance (c) a cell (d) a battery of three cells (e) an open switch (f) a closed switch.

Answer 1

The circuit symbols for (a) fixed resistance (b) variable resistance (c) a cell (d) a battery of three cells (e) an open switch (f) a closed switch (Please refer the attachment)

Explanation:

(a) Fixed Resistance: Resistance of a resistor is constant throughout.

(b) Variable Resistance: Resistance that adjusts to control the voltage or current as per the requirement.

(c) A Cell: An electrical energy source that produces current using chemical reactions.

(d) A Battery of Three Cells: 3 one cell batteries put together to achieve or control the voltage as desired.

(e) An Open Switch: A switch that does not allow current to flow through it.

(f) A Closed Switch: A switch that allows the current to flow through it.
