tahellemadenko01, let's knock this out. 28. The component used to vary resistance in an electric circuit is called: A component designed to vary resistance in an electric circuit is known as a rheostat. C. Rheostat 29. The total resistance of the circuit in Figure 4 is Step 1: Calculate the equivalent resistance of the two parallel resistors (R_p). The resistors are 3 Ω and 6 Ω. (1)/(R_p) = (1)/(3 Ω) + (1)/(6 Ω) (1)/(R_p) = \
