Question

In the circuit shown below, the battery delivers 17.3 W of power. (a) Find the equivalent resistance Req1 of the entire circuit (you don't need to know R, use the power information). (b) How much current flows through the battery? (c) What is the equivalent resistance of the entire inside branch of the circuit from point B to point D? (just through the 6.0, 8.0 and 2.0 ohm resistors, not through resistor R) (d) Write an expression for the equivalent resistance of all paths from B to D (just leave the resistance R as a symbol in your expression). (e) Find the resistance R in the right-most branch of the circuit. (f) Assuming the negative battery terminal is at zero volts, what is the potential at point B? (g) How much current flows through resistor R?
