Question 2
a.

Determine which one of the following resistors, connected in parallel with a 36.0 Ω36.0\ \Omega36.0 Ω resistor, would give a total equivalent resistance of 12.0 Ω12.0\ \Omega12.0 Ω. Show your working.

Available resistors: 4.0 Ω4.0\ \Omega4.0 Ω, 6.0 Ω6.0\ \Omega6.0 Ω, 9.0 Ω9.0\ \Omega9.0 Ω, 12.0 Ω12.0\ \Omega12.0 Ω, 18.0 Ω18.0\ \Omega18.0 Ω, 24.0 Ω24.0\ \Omega24.0 Ω, 27.0 Ω27.0\ \Omega27.0 Ω, 48.0 Ω48.0\ \Omega48.0 Ω

b.

The parallel combination of the 36.0 Ω36.0\ \Omega36.0 Ω resistor and the resistor identified in part (a) is connected in a circuit across a 9.0 V9.0\text{ V}9.0 V battery.

Describe where an ammeter should be placed in the circuit to measure only the current in the 36.0 Ω36.0\ \Omega36.0 Ω resistor.

c.

Calculate the current flowing in:

  1. the 36.0 Ω36.0\ \Omega36.0 Ω resistor.
  2. the other resistor identified in part (a).
