Two wires A and B have the same cross-section and are made of the same material. Ra=600Ω and Rb=100Ω. The number of times A is longer than B is Which of the following statement is TRUE both for a series and a parallel dc circuit? a. powers are additive b. voltages are additive c. currents are additive d. elements have individual currents Kirchhoff’s current law is applicable to only a. closed loops in a network b. electronic circuits c. junctions in a network d. electric circuits Two resistors are said to be connected in series when a. both carry the same value of current b. total current equals the sum of branch currents c. sum of IR drops equals the applied emf d. same current passes in turn through both According to KCL as applied to a junction in a network of conductors a. total sum of currents meeting at the junction is zero b. no current can leave the junction without some current entering it c. net current flow at the junction is positive d. algebraic sum of the currents meeting at the junction is zero The algebraic sign of an IR drops is primarily dependent upon the a. amount of current flowing through it b. value of R c. direction of current flow d. battery connection Materials with lots of free electrons are called a. conductors c. semiconductors b. insulators d. filters
