Quelle est la puissance totale consommée par deux résistances de 10 ohms branchées en série aux bornes d'une pile de 10 volts?

Why

With two 10-ohm resistors in series, the total resistance becomes 20 ohms, which limits the current flowing from the 10-volt battery to 0.5 amperes. The full explanation — and one for every question — is in Pro.
