We can also have voltage sources whose values are dependent on some other element in the circuit A dependent source is indicated with a diamond shape For example, if there is some current i(t) in the circuit, a voltage source that varies with i(t) as v(t) = ri(t), where r is a constant is illustrated by the diamond shown in Fig 1-8

We can also excite a circuit by supplying a current from an external source In the same way that a voltage source can be thought of as a black box, the internal construction of a current source is not of any concern in circuit analysis In a real circuit, a current source may be a transistor circuit that supplies current to some other circuit that is being analyzed But we don t care what the internal construction is we only care about what current i(t) the current source supplies Simply put, a current source is a circuit element that always has a speci ed current owing through it A current source behaves in an inverse manner to a

voltage source While a voltage source operates at a xed voltage and the current owing through it is determined by the other components in the circuit, a current source always has a speci ed current owing through it and the voltage across it is determined by what elements are connected to it in the circuit A current source is shown in a circuit diagram by drawing a circle that contains a current arrow in it As usual, the arrow indicates the direction of ow of positive charge An example is shown in Fig 1-9 It is also possible to have dependent current sources These are indicated with a diamond shape containing an arrow indicating the direction of the current The current that ows through the element can be dependent on some other quantity in the circuit For example, the current can be dependent on some voltage v(t) using the relation i(t) = gv(t), where g is a constant This is shown in Fig 1-10

Open and Short Circuits
We are nearly done with our tour of the foundational elements of circuit analysis Next we consider two terms that are common in the English language, open circuits and closed circuits Your common sense view of an open circuit is probably accurate You can think of it as basically an open switch In fact, as shown in Fig 1-11, we indicate an open circuit by a drawing of an open switch in a circuit diagram As you might guess from the fact that an open circuit has a switch that is open, there is no conducting path through an open circuit In other words the current through an open circuit is i = 0 However, an open circuit can have a voltage across it A short circuit has no voltage across it, so v = 0 However, a short circuit is a perfectly conducting path We indicate a short circuit by drawing a straight line in a circuit diagram

An Introduction to Circuit Analysis
Power
We conclude this introductory chapter with a look at power The SI unit used for power is the watt, where 1 W = 1 J/s (116)
We often write W to indicate watts In electric circuit analysis, power is the product of voltage and current Recall that the units of voltage are joules/ coulomb and the units of current are coulombs/second, so if we form the product coulombs cancel giving joules/second or watts If we denote power by p(t), then p(t) = v(t) i(t) (117)
The power in a circuit element can be positive or negative, and this tells us whether or not the circuit element absorbed power or if it is a power supply If the power in a circuit element is positive p = vi > 0 then the element absorbs power If the power is negative p = vi < 0 then the element delivers power to the rest of the circuit In other words it is a power supply When analyzing the power in a circuit, we examine the direction of the current arrow relative to the signs indicated for the voltage If the current arrow points in the direction from the + to signs along the voltage (ie, along a voltage drop), then the power is positive This is shown in Fig 1-12 Remember that, if the current in Fig 1-12 is negative, the power will be negative as well So if v(t) = 5 V and i(t) = 3 A, the power for the element in Fig 1-12 is p = (5 V) (3 A) = 15 W
