Trig identities Essential Identities sin( + ) = sin cos + cos sin cos( + ) = cos cos sin sin sin( ) = sin() cos( ) = cos() Some Derived Identities sin( ) = sin cos cos sin cos( ) = cos cos + sin sin sin cos = s...
Steady-State Sinusoidal Analysis - Without a time element to a signal, we can analyse sinusoidal signals with complex numbers, using the magnitude and phase of the signal. - A sinusoid is a signal that...
Maxwells Equations Maxwells equations completely describe electromagnetic interactions They are analogous to newtons laws of motion The electric flux through a closed surface is proportional to the total charge enclosed...
- In DC, inductors are a short circuit since a magnetic field is only generated by a changingelectric field. + - I0= i(0 ) = i(0 ) Power through an inductor - p = Li didt ...
V is the voltage between the two components This only comes from the voltage of the battery if the capacitor is fully charged. Otherwise dQ dV dV (t) dt = C dt i(t) = C dt v(t) = 1 tid + v(t0) C t 0 w = 21Cv 2 The cap...
Capacitors and Inductors Admittance and Impedance Impedance is the AC analogue of DC resistance and is measured in ohms. Slightly more complicated because you have to consider the frequency of the current. Capacitors 1 ...

assume that the one you are focused on then is positive and subtract the other one v = 5(ia i b . 4. Doing this for all meshes, you will end up with enough equations to come up with a complete solution a. Protip; solve usi...
a. What were trying to find with this method is the voltage at each node (relative to the voltage source) 4. Label the essential nodes 1, 2, 3, then, mark the polarity on the essential nodes relative to the reference node ...
Nodal Analysis, Mesh Analysis and Other Methods Some terminology - Planar Circuit:A circuit that can be drawn on a plane with no overlapping branches - Node:A point where 2 or more circuit elements join - ...
The equivalent resistance of a circuit can be found by removing the power sources Voltage sources are replaced with a short circuit Current sources are replaced with an open circuit. A circuit consisting of some compon...
Where is some constant representing the resistivity of the material Units are m (ohm meters) Resistors in series All resistors in series have the same current magnitude. The total resistance of a circuit of resistors i...
The unit of resistance is the ohm denoted by an omega Ohms law v=iR Talking about current in resistor and terminal voltage. When we talk about the voltage drop across a resistor, use V = IR Tolerance V = I(R R) Us...
The common mode gain is A but when the inverting and non inverting amplifiers are joined at some node In theory, this is 0, causing a CMRR of 0 We want the signal to noise ratio to be high James Boric 17 ELEC1103
