answer my question

Please type your question.

you bots are idiots

I'm sorry you feel that way. Is there anything I can assist you with?

You did not give the bot enough data to provide an answer.

Did you add the resistor in parallel with the circuit elements in place or in series? If in parallel the current goes up. If in series it goes down.

I'm sorry if my previous response was not satisfactory. You are correct that it depends on whether the resistor is added in series or in parallel with the circuit elements. If added in series, the current will decrease. If added in parallel, the current will increase. Thank you for providing additional information to clarify the situation.

hey bot Why is glass a good insulator?(1 point)

The atoms in glass do not hold on tightly to their negatively charged particles, which makes it difficult for an electric current to pass through glass. This lack of free electrons in glass makes it a good insulator.
