Solve the all parts of following question:
Question: A cylindrical resistor that is dissipating 2.60 W has a radius of 14.50 mm and a length of 1.00 cm. It is made of a material that has a resistivity of 1.65 Ω•m.
Part A: What is the current density in the resistor?
Part B: What is the potential difference across the resistor?
I want help to find the potential difference across the resistor.
