The total resistance isTwo resistors of $10\Omega$ each are connected in PARALLEL. The total resistance isA $12\,\text{V}$ battery drives a current of $2\,\text{A}$ through a resistor. The POWER dissipated isTHEVENIN'S THEOREM states that any linear two-terminal network can be REPLACED byNORTON'S THEOREM gives an equivalent network asFor MAXIMUM POWER TRANSFER from a source with internal resistance $R_S$ to a load $R_L$, we needTwo batteries of $10\,\text{V}$ and $5\,\text{V}$ are connected in series-aiding (same polarity). The combinedAn ideal AMMETER has internal resistanceSUPERPOSITION THEOREM applies toA capacitor in a DC circuit, in STEADY STATE, acts asAn inductor in a DC circuit, in STEADY STATE, acts asAn AC voltage is described as $v(t) = V_m in(\omega t)$. $V_m$ isFor a sinusoidal AC voltage with peak $V_m$, the RMS value isThe angular frequency $\omega$ (rad/s) relates to the frequency $f$ (Hz) asThe IMPEDANCE of a pure capacitor at angular frequency $\omega$ isThe IMPEDANCE of a pure inductor at angular frequency $\omega$ isIn a series RLC circuit, RESONANCE occurs at the frequency whereThe resonant frequency of an LC circuit with $L = 100\,\text{mH}$ and $C = 1\,\mu\text{F}$ is closest toPOWER FACTOR is defined asA purely RESISTIVE AC load has voltage and current that areIn an AC circuit with a pure INDUCTOR, the currentIn an AC circuit with a pure CAPACITOR, the currentAn RMS AC voltage of $230\,\text{V}$ drives a $100\Omega$ RESISTIVE load.
