Acircuit contain a 5-ohm, a3-ohm, and an 8-ohm resistor in series. what is the total resistance of the circuit ?

What are two different ways you could find the value of a? explain these methods.

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.

If an electric circuit is not grounded it is best to reach out and touch it to provide the ground a.true or b.false
