24.ECE Board Exam November 1998 If a resistance element is part of two loops, how many voltage drops must be calculated for that component?

• Two

• Three

• One

• none

How many nodes are needed to completely analyze a circuit according to Kirchhoff’s current law?

• one

• two

• one less than the total number of nodes in the circuit

• all nodes in the circuit

In order to match the load to the generator means making load resistance

• lower than generator’s internal resistance

• increased to more generator’s internal resistance

• decreased

• equal to generators internal resistance

In the Norton’s equivalent circuit, the source is a

• constant voltage source

• constant current source

• constant voltage and constant current

• none

The superposition theorem requires as many circuits to be solved as there are

• meshes

• source

• nodes

• all of the above

An active element in a circuit is one which

• receives energy

• supplies energy

• both receives and supplies energy

• none of the above

An passive element in a circuit is one which

• supplies energy

• receives energy

• both receives and supplies energy

• none of the above

An electric circuit contains

• active elements only

• passive element only

• both active and passive elements

• none of the above

linear circuit is one whose parameters (e.g. resistances etc.)

• change with change in current

• change with change in voltage

• do not change with change in voltage and current

• none of the above

The superposition theorem is used when the circuit contains

• a single voltage source

• a number of passive source

• passive elements only

• none of the above
