Question

Name the device we use to maintain the potential difference in a circuit

Answer 1

Answer:

across a conductor it is a battery which maintains the potential difference

Explanation:

Answer 2

ANSWER:

• Cell / Battery is use to maintain the potential difference in a circuit.

MORE EXPLANATION

• BATTERY: When two or more cell combine together then it is called a battery.
• POTENTIAL DIFFERENCE : The work done to take 1 columb of charge from one point to other is called potential difference.
• ELECTRIC POTENTIAL : The work done to take 1 columb of charge from INFINITY to any other point is called electric potential.
• It is only with the help of potential difference that the current flows.
• Current flows from higher potential to lower potential.
• As water flows from upper to lower surface.

SOME IMPORTANT FORMULAS:

$\implies \: v = \frac{w}{q} \\ \implies \: v = i \times r \\ \implies \: p \: = v \times i \\ \implies \: i \: = \frac{q}{t}$

where:

• v = potential difference
• w = work done
• I = current
• p = power
• r = resistance
• q = charge
