The voltage in a circuit is given by the equation v=ir. in this equation, v is the voltage, i is the current, and r is the resistance. which answer shows this equation solved for current?

a. i = v/r
b. i = r/v
c. v = i/r
d. i = vr

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.
