What is voltage amplitude?
Voltage amplitude is the maximum value of a voltage.
How can instantaneous current values be determined?
Voltage divided by the resistance of what ever you want to measure the current in.
Why must the instantaneous current wave be exact 90 degree out-of phase with the applied voltage waveform across an ideal inductor?
Because the voltage induced is proportional to the rate of change of current, and the maximum rate of change of current occurs at the point where the current waveform is 'steepest' -i.e. as it passes through zero. So, as the current passes through zero, the corresponding value of induced voltage is maximum, which means the voltage and current waveforms are displaced by a quarter of the wavelength, or 90 degrees.
What is the instantaneous voltage of 90 degrees?
The instantaneous voltage at 90 degrees in a sinusoidal waveform is at its peak value, as this angle corresponds to the maximum point of the sine function. Mathematically, if the voltage is represented as ( V(t) = V_{\text{max}} \sin(\omega t + \phi) ), at 90 degrees (or ( \frac{\pi}{2} ) radians), the voltage is ( V(t) = V_{\text{max}} ). Thus, the instantaneous voltage is equal to the maximum amplitude of the waveform.
What is the voltage at 90 degrees if the instantaneous voltage is 225v at 60 degree angle?
To find the voltage at 90 degrees given an instantaneous voltage of 225 V at a 60-degree angle, we can assume a sinusoidal function for the voltage. The voltage can be represented as ( V(t) = V_m \sin(\theta) ), where ( V_m ) is the maximum voltage. Since you provided the instantaneous voltage at 60 degrees, you can calculate the maximum voltage ( V_m ) using ( V_m = \frac{225}{\sin(60^\circ)} ). Then, to find the voltage at 90 degrees, you would evaluate ( V(t) ) at that angle, resulting in ( V(90^\circ) = V_m \sin(90^\circ) = V_m ).

What is alternative voltage?
Alternating voltage is the E.M.F. and is one whose magnitude whose magnitude changes with time and direction reverses periodically. The instantaneous value is given by E=Eo sin w t, where,E=value of alternating voltage at time t Eo = maximum value of alternating voltage(amplitude) w=angular frequency of supply.

What is the instantaneous voltage of a sine wave at 25 degrees if its peak voltage is 30 V?
12.68V 3o * sin25 = 12.67854785
What is the relation between amperage and capacitance?
The relationship between amperage and capacitance is indirect. Capacitance stores and releases electrical energy, affecting the flow of current in a circuit. Higher capacitance can lead to slower changes in current (i.e., lower frequency), while lower capacitance can result in faster changes in current.
What is the formula for instantaneous current?
The formula for instantaneous current (i) in a circuit is given by Ohm's law: i = V / R, where V is the voltage across the circuit and R is the resistance.
What is voltage amplitude?
Voltage amplitude is the maximum value of a voltage.
What is instantaneous power mean?
Instantaneous power refers to the power being consumed or generated at a specific moment in time. It is calculated as the product of the voltage and current at an exact instant and represents the rate at which energy is being transferred or converted at that particular point. It is commonly used in electrical engineering to analyze dynamic power consumption in circuits or systems.
If the peak voltage of a sine wave is 100 volts then the instantaneous voltage at 150 and deg is volts?
To find the instantaneous voltage of a sine wave at a given angle, you can use the formula ( V(t) = V_{peak} \cdot \sin(\theta) ). For a peak voltage of 100 volts and at 150 degrees, convert 150 degrees to radians if necessary or use the sine function directly. The sine of 150 degrees is 0.5, so the instantaneous voltage is ( 100 \cdot \sin(150^\circ) = 100 \cdot 0.5 = 50 ) volts.
