WebIn an AC circuit - alternating current is generated from a sinusoidal voltage source Voltage Currents in circuits with pure resistive, capacitive or inductive loads. The momentary voltage in an sinusoidal AC circuit can be expressed on the time-domain form as u (t) = Umax cos (ω t + θ) (1) where u (t) = voltage in the circuit at time t (V) WebFor example, if the voltage and current variables are the voltage across and current through a resistor, then we know V = I R and thus that the current will change proportionally with the voltage. However, if a diode instead of a resistor, we have I = I S e V n V T and thus the current will change exponentially with the voltage.
