Which of the following is not the reason why concrete needs reinforcement? A: Reinforcement has good tensile resistance, while concrete has good compressive resistance. B: Reinforcement has good compressive resistance as concrete. C: Engineers prefer ductile failure to brittle failure of the members. D: Reinforcement and concrete can work together to increase the bearing capacity of the members.

Ohm’s Law states that current equals voltage divided by resistance. Current increases with the increase in voltage. Current decreases with the increase in resistance.
