If every resistor below has resistance R, what is the equivalent resistance of the combination, in terms of R?

You have a 2.0 Ω resistor, a 3.0 Ω resistor, a 6.0 Ω resistor, and a 6.0 V battery. Draw a diagram of a circuit in which all three resistors are used and the battery delivers 9.0 W of power.

Draw a circuit diagram for the circuit of FIGURE EX28.2.

What is the equivalent resistance of a$4.0\Omega$ resistor in parallel with a$6.0\Omega$ resistor?

What is the equivalent resistance of a$4.0\Omega$ resistor in series with a$6.0\Omega$ resistor?

Three identical resistors are in parallel, and together they have an equivalent resistance of R. What is the resistance of each resistor?

Light Bulbs in Series and in Parallel. Two light bulbs have constant resistances of 400Ω and 800Ω. The two light bulbs are connected in series across a 120-V line. Afterwards, the two light bulbs are connected in parallel across the 120-V line. (h) In which situation is there a greater total light output from both bulbs combined?
