Question

In a four-branch parallel circuit, there are 10 mA of current in each branch. If one of the branches opens, what is the current in each of the other three branches?           

      0 mA
      10 mA
      13.3 mA
      30 mA

A circuit consists of two 1.0 k%u03A9 resistors in series and this series being connected in parallel to a 570 %u03A9 resistor.

If the voltage drop across one of the 1.0 k%u03A9 resistors is 4.5 V, what is the voltage drop across the 570 %u03A9 resistor?
