1. Use the principle of superposition to solve for Vx. Think about what kind of sources we turn off for each step. Draw the circuit for each case in which you are calculating a source's contribution to the desired value. Remember that the desired value here is Vx 12 V + 6 ΚΩ ww 0.5 mA M +Vx - 0.5Vy + Vy ww 4 ΚΩ O 5 mA

For the following circuit, assume constant-voltage model and VB = 2 V. Plot the input/output characteristic. R1 Vout Vino D1 R2 V D2 + 'VB

The circuit in Figure has been connected for a long time. If the battery is disconnected, how does it take the capacitor to discharge to 1/20 of its initial voltage? Take R₁ = 2.00 Q, R₂=4.00 Q, R3-7.00 Q, R4 = 2.00 Q and C= 5.00 uF and ε = 14.0 V. (Your result must be in us. Include 2 digit after the decimal point and maximum of 2% of error is accepted in your answer.) E R₂ R₂ BA
