-ve sign is used to state Lenz law - ε oppose change change in Φ inside loop Additional capacitor in parallel - Like adding more A to the first capacitor so more Q can be stored Alternating current (AC) - Produces V and I that vary with time. Polarity of V and direction of I regularly reverses. Supply f gives no of ω (angular frequency) cycles of this reversal in polarity or direction per sec. ω = 2πf Applying Kirchhoff's Voltage law through a power supply - When moving through a pow...
