Equivalent Resistors Introduction The circuits in this set of problems consist of several resistors and an ohmmeter. The resistors are connected together to form a “resistor sub-circuit”. The ohmmeter measures the equivalent resistance of the resistor sub-circuit. These circuits can be simplified by repeatedly replacing series or parallel resistors by an equivalent resistor. Eventually, the resistor sub-circuit is reduced to a single equivalent resistor. The ohmmeter measures the resistance of that single equivalent resistor. (What is a “sub-circuit”? It’s part of a circuit. What is the “equivalent resistance” of a resistor sub-circuit? When we reduce the resistor sub-circuit to a single equivalent resistor as described above, the equivalent resistance is the resistance of the equivalent resistor.) Series resistors are discussed in Section 3.4 of Introduction to Electric Circuits by R.C. Dorf and J.A Svoboda. Parallel resistors are discussed in Section 3.5. Equivalent resistance is described in Section 3.7. Worked Examples Example 1: Consider the circuit shown in Figure 1. Find the value of the resistance R . Figure 1 The circuit considered in Example 1. Solution: The terminals in Figure 1 divide the circuit into two parts, the part to the left of the terminals and the part to the right of the terminals. The part to the left of the terminals consists of 1

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
