A loop has two batteries of 10 V and 5 V connected in opposition with internal resistances of 1 Ω each. The total current in the circuit is:

Three resistors of 8 Ω each are connected in parallel. What is the equivalent resistance of the combination?

What is the electric power consumed by a 40 Ω resistor connected directly across a 12 V DC battery?

A 24 V DC circuit has a 4 Ω resistor, a 2 Ω resistor, and an ammeter of resistance 0.5 Ω connected in series. Find the current flowing through the circuit.
