What charge will pass through a 10 Ohm conductor in 20 s if a voltage of 12 V is applied to its ends?

Initial data: R (conductor resistance) = 10 Ohm; t (time) = 20 s; U (voltage applied to the ends of the conductor in question) = 12 V.

1) We calculate the current in the conductor under consideration (Ohm’s law for a section of the circuit): I = U / R = 12/10 = 1.2 V.

2) Determine the desired charge that passed through the conductor: q = I * t = 1.2 * 20 = 24 C.

Answer: A charge equal to 24 C will pass through the conductor in question.
