current of 5A is flowing per second in 4 Ohm resistance. Find the potential difference and heat generated.

Current flow in conductor per second = 5A

Resistance of conductor = 4Ω

We have to find potential difference and heat generated .

★ As per ohm's law, current flow in conductor is directly proportional to the applied potential difference.

V = IR

V denotes potential difference

I denotes current

R denotes resistance

Potential difference :

→ V = IR

→ V = 5 × 4

→ V = 20 volt

Heat generated :

→ H = I²R × t

→ H = 5² × 4 × 1

→ H = 25 × 4

→ H = 100J

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
