Question

What is the symbol for a battery?
A.)

B.)

C.)

D.)

Answer 1

Hint: A battery consists of one or more electrochemical cells. In a battery one terminal is positively charged and one terminal negatively charged. When a circuit is closed the electrons will flow from negative terminal to positive terminal which will create current inside the circuit.

Complete step by step answer:
The symbol for battery is

Represents an open switch and

represents a closed switch.

This represents a bulb.
Hence, the correct answer is option A.

Additional Information
Circuit Diagram: It is a diagram which shows how the different components of a circuit are connected together. The different circuit components are cell,battery(combination of cells).switch(open) and switch(closed), bulb, resistance, rheostat, ammeter, voltmeter, galvanometer. Different circuit symbols of a circuit are given below table

Cell
battery
Switch(open)
Switch(closed)
resistance
bulb
voltmeter
ammeter

(I)Ammeter: It is an electronic device used to measure the amount of current flow in terms of $Ampere$ a mili-Ampere. An ammeter always connected in series with the circuit.
(II)Voltmeter: It is an electronic device used to measure the potential difference between two points in terms of $Volt$. Voltmeter always connected parallel with the circuit.
(III)Galvanometer: It measures a very small potential difference between two points.

Note:
In a circuit the direction of current is from positive end to negative end (opposite to direction of charge flow). The longer end of the battery is positive and the shorter end is negative. The positive end of the ammeter is always connected to the positive end of the battery and negative end of the ammeter connected to the negative end of the battery. Ammeter is connected in series whereas voltmeter and galvanometer were always connected in parallel with the circuit.
