Question
The circuit in Figure P18.52a consists of three resistors
and one battery with no internal resistance. (a) Find the current
in the 5.00 - Ω resistor. (b) Find the power delivered to the
5.00 - Ω resistor. (c) In each of the circuits in Figures P18.52b,
P18.52c, and P18.52d, an additional 15.0 - V battery has been
inserted into the circuit. Which diagram or diagrams represent
a circuit that requires the use of Kirchhoff’s rules to find
the currents? Explain why. (d) In which of these three new circuits
is the smallest amount of power delivered to the 10.0 - Ω
resistor? (You need not calculate the power in each circuit if
you explain your answer.)
