Ohm's law - Impossible During a time interval of 15 s, a charge of 50 C flows through a conductor. What is the intensity of the electric current? Determine the resistance of a copper wire whose length is 30 m and a cross section is 6.8 x 10 ^ −6 m2. (rho = 1.72 x 10 ^ -8 m Ω) Determine the intensity of the electric current through a 40 Ω resistor by applying a potential differential of 120 V. Calculate the potential difference applied to a 10 Ω resistor and 2 A flows through it. Determine the power of a refrigerator whose voltage is 120 V and the intensity of the electric current is 3.5 A. With reference to the refrigerator, how much energy does it consume if it runs for 8 hours?
