Consider the circuit shown below. Find the power dissipated by the resistor R2 (in W). Kirchhoff's Current Law According to Kirchhoff's current law, in an electrical circuit, the net current flowing into a junction always equals the net current flowing out of the j...
For the circuit shown in the figure, determine the power dissipated by the resistorR2. Power Dissipation in Resistor: Power dissipation is described as the amount of electric energy that gets transformed into heat. The resistors are passive elements which cause loss of powe...

A current of 2.5 A flows through a resistor where a potential difference of 20.0 V is maintained. What is the power dissipated by the resistor? 2. Determine the power dissipated by a resistor if it carries a current of 4 A with a potential difference of 40 V maintained...
Method A: Assume a voltage source υi is connected to the input and find Zo = υo,open-circuit/io,short–circuit. Method B: Short out υi. Connect a voltage source υ to the output and calculate the resulting current i; then Zo = υ/i. 12. A load resistor RL′ is connected to...
(In simple analysis, this gate current is assumed to be zero for an ideal capacitor.) The MOSFET uses an input voltage to control an output current. In many cases, this current is passed through a resistor to produce a voltage. By connecting the MOSFET with resistors (and capacitors), ...

Power is a measure of the rate of work. Per the physics law of conservation of energy, the power dissipated in the circuit must equal the total power applied by the source(s). Therefore, an interesting rule for total circuit power versus individual component power is that it is additive fo...
Some regulators combine a current limit function with the IMON pin. The pin may be called IMON/ILIM. Be careful not to select an IMON resistor value such that the IMON voltage activates the current limit circuit under full load. Examples include linear regulators, such as theLT3072a...
Figure 3. Efficiency measurement circuit using 4 DMMs. Figure 4. MAX34407 efficiency measurement vs. 4-DMM method. There is a notable offset in the two methods, and this stems from the power dissipated in the output current-sense resistor. Since MAX34407 measures the common-mode ...
