Draw the symbols of the following electrical components.
(i) Battery
(ii) A.C. source
(iii) Rheostat
(iv) Open key
Answers
(i)battery
is a right answer
Answer:
Explanation:
A battery is a device that converts chemical energy into electrical energy in the form of voltage, which in turn can cause current to flow. Please refer to the attached picture number 1 for the symbol of battery in an electric circuit.
Alternating current (ac) is the flow of electric charge that periodically reverses direction. Please refer to the attached picture number 2 for the symbol of ac source in an electric circuit.
A Rheostat is a variable resistor, a device using which the electric resistance value can be adjusted. It works by sliding a wiper terminal across a resistive material, typically a thin film or chunk of carbon or a resistive wire made of nickel chromium or tungsten alloys. Picture 3 shows symbol.
A switch is said to be open when no current is drawn from the cell, and the circuit is open or incomplete. The electric appliance is said to be 'off' when the switch is in open condition. Contrarily, when the switch is closed, current is drawn from the cell and the circuit is complete. Picture 4 shows symbol.
