An alternating current source has an output voltage given by the expression:
∆𝑉 = 200 𝑠𝑖𝑛 ( 20𝜋𝑡 ) where ∆𝑉 is in volts.
What is the source frequency and its maximum current when it is connected to a 50 𝛺 resistor?
f = 10 Hz
Max Current = 2.8A
f = 10 Hz
Max Current = 3.0A
f = 10 Hz
Max Current = 4.0A
f = 20𝜋 Hz
Max Current = 4.0A
