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

Write a hypothesis about the effect of increasing resistance on the current in the circuit. use theformat and be sure to answer the lesson question. “how do changes in voltage or resistance affect current in an electric circuit? ”
