Chapter 6.2, Problem 1cT

Predict the relative brightness of bulbs ${\text{B}}_{\text{1}}\text{,}{\text{B}}_{\text{1}}\text{,}\text{and}{\text{B}}_{\text{3}}$ in the circuits shown. (A dashed box has been drawn around the network of circuit elements that is in series with each of these bulbs.)

What does your prediction imply about the relative currents through the batteries? Explain.

Have a tutorial instructor show you these circuits so that you can check your answers.
Resolve any conflicts between your answers and your observations.
