Instantaneous Voltage Formula
The following formula is used to calculate the Instantaneous Voltage.
IV = Vmax * Sin (w*t)
- Where IV is the Instantaneous Voltage (volts)
- Vmax is the maximum voltage (volts)
- w is the angular frequency (rad/s)
- t is the time (s)
How to Calculate Instantaneous Voltage?
The following example problems outline how to calculate the Instantaneous Voltage.
Example Problem #1
- First, determine the maximum voltage (volts). In this example, the maximum voltage (volts) is determined to be 100 .
- Next, determine the angular frequency (rad/s). For this problem, the angular frequency (rad/s) is measured to be 4 .
- Next, determine the time (s). In this case, the time (s) is found to be 3.
- Finally, calculate the Instantaneous Voltage using the formula above:
IV = Vmax * Sin (w*t)
Inserting the values from above into the equation gives:
IV = 100* Sin (3*4) = -53.65 (volts)
Example Problem #2
Using the same method as above, determine the variables required by the equation. For this example problem, these are provided as follows:
maximum voltage (volts) = 200
angular frequency (rad/s) = 5
time (s) = 6
Entering these given values into the calculator above yields:
IV = 200 * Sin (5*6) = -197.606 (volts)
