The total current supplied to the circuit by the battery is
Show Hint
When resistors are connected in series, they form a single pathway for the flow of current.
- 1 A
- 2 A
- 4 A
- 6 A
The Correct Option is A
Solution and Explanation
In this circuit, 2Ω and 6Ω resistors are connected parallelly, 2Ω ∥ 6Ω = (2 x 6)/ (2 + 6) = 12/8 =1.5Ω
Then, all these 3 resistors are connected in series: ∴ Req = 1.5 + 1.5 + 3 = 6Ω
Hence, the total current that is supplied to the circuit by the battery is, I = V/Req = 6V/6Ω = 1A
Therefore, the correct answer is The total current supplied to the circuit by the battery is Option A) 1A

Electric Current
Defining Electric Current
It is the rate of flow of electrons in a conductor. SI Unit - Ampere (A).
Electrons are negatively charged particles hence when they move a number of charges moves.
Note:- The ability of a particular substance to conduct electricity depends on the number of electrons that are able to move . Some of the materials allow current to flow better than others.
What is an Electromotive Force?
If a force acts on electrons to make them move in a particular direction, then up to some extent random motion of the electrons will be eliminated. An overall movement in one direction. The force which acts on the electrons to move them in a certain direction is known as electromotive force and its quantity is known as voltage and is measured in V.
