Question

A resistor is constructed of a carbon rod that has a uniform cross-sectional area of 5.00 mm^2. When a potential difference of 15.0 V is applied across the ends of the rod, there is a current of 4.00x10^-3 A in the rod. Find the rod's length for carbon Ï=3.5x10^-5.

Name: a resistor is constructed of a carbon rod that has a uniform cross sectional area of 500 mm2 when a potential difference of 150 v is applied across the ends of the rod there is a current of 39062

Step 1

0 V), I is the current (4.00x10^{-3} A), and R is the resistance. R = V/I = 15.0 V / (4.00x10^{-3} A) = 3750 Ω Show more…
