Por un alambre de cobre circula una intensidad de corriente de 5 A en 120 segundos, ¿Cuál es la cantidad de carga que circula por el alambre de cobre

the answer is to check all of them! they all apply well at least i think so!

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
