A 24 V potential difference is applied across a parallel combination of four 6 Ω resistors. Find the current flowing through each resistor.

In a parallel combination of resistors, the voltage across each resistor will be the same that is 24 V.
In the given parallel combination, all the resistors have the same resistance value of 6 Ω.
Therefore, the current in each resistor can now simply be calculated using the relation,
 $\mathrm{I} = \frac{\mathrm{V}}{\mathrm{R}}$

$\mathrm{I} = \frac{24}{6}$

$\mathrm{I} = 4.0 \mathrm{A}$

Therefore, when a 24 V potential difference is applied across a parallel combination of four 6 Ω resistors, 4 A current will flow through each resistor.
