WebWhat is the current in the resistor? Using Ohm's Law, i = v/R gives us i = (A sin wt) / R. So when the voltage is a sinusoid, the current is a sinusoid, too. In general, if you define either v or i to be sinusoidal, the other will follow along and be sinusoidal, too. In a resistor, the sinusoidal i and v are lined up with each other in time. WebSep 12, 2024 · We can calculate the current density by first finding the cross-sectional area of the wire, which is \(A = 3.31 \, mm^2\), and the definition of current density \(J = …
WebUsing the formula below, the current in the resistor is given by: where ZC = 1/ (jωC) is the impedance of the capacitor and j is the imaginary unit . The product τ = CR is known as the time constant of the circuit, and the frequency for which ωCR = 1 is called the corner frequency of the circuit.
WebVolts calculations. The voltage V in volts (V) is equal to the current I in amps (A) times the resistance R in ohms (Ω): The voltage V in volts (V) is equal to the power P in watts (W) divided by the current I in amps (A): The voltage V in volts (V) is equal to the square root of the power P in watts (W) times the resistance R in ohms (Ω): raiders vs seahawks todayWebHere you will find that a voltage source with series resistance can be modeled as a current source with parallel resistor.
