Question

49. In an electric circuit the function of the battery is to
A Control the current
B. Maintain the potential difference
C. Measure the current
D. Measure the potential difference​

Answer 1

Answer:

The key functions of a battery and bulb in a circuit are explained. A battery is a source of energy which provides a push - a voltage - of energy to get the current flowing in a circuit. A bulb uses the electrical energy provided by the battery, but does not use current.

Answer 2

Answer:

Correct answer is A) Control the current

The function of the battery is stated below.

Explanation:

First of all, a battery does not provide electrons, but its function is to spin/flow electrons that are already in orbit around it (overview).

It has two main functions.

First, a current can flow through a circuit by applying an electric field in the circuit to move electrons and produce current.

Second, there is a non-electrostatic field inside the battery, so every time an electron enters the battery, the field does the work of moving the electron from the +ive terminal to the -ive terminal (ie, the vs. electrostatic field).  After receiving this energy, the electron starts moving in the circuit again and every time it reaches a resistance, it loses this potential energy (known as voltage drop) and again this electron goes back to recharge.
