Question

A battery provides a potential difference of 14V. What size current will flow through a 10 ohm resistor in this circuit?

Answer 1

Answer :

• Current flowing through the circuit is 1.4 ampere

_________________________

Given :

• Potential Difference ( V )= 14 V

• Resistance ( R )= 10 ohm

To Find :

• Current ( I )

Solution :

• According to the Ohm's Law , V = IR

Now , substitute the given values :

$\implies \sf Current \:=\: \dfrac{V}{R}$

$\implies \sf Current \:=\: \dfrac{14}{10}$

$\implies \sf Current \:=\: 1.4\:ampere$

• Current flowing in this circuit is 1.4 A

Answer 2

Given:

A battery provides a potential difference of 14V.

To find:

Current through a 10 ohm resistance ?

Calculation:

• Potential difference refers to the work done to transport charge within an electric field. Similarly, for current , it is defined as the rate of flow of charge.

• So, as per OHM'S LAW :

$V = i \times R$

$\implies \: i = \dfrac{V}{R}$

$\implies \: i = \dfrac{14}{10}$

$\implies \: i = 1.4 \: amperes$

So, charge through the circuit is 1.4 Ampere.
