Voltage across a resistor

  • #1

Homework Statement


The voltage V(t) [in volts] across a resistor in an electrical circuit at a given time t [in seconds] is given by:

sqrt of something to the power of pi

^ that's the example i got in my book. Its just got the square root symbol, a space, and then a pi in an exponential position.

power as a function of time: p(t)=v(t) · i(t)

Ohm's Law: v(t)=R · i(t)

The nearest matching your case that I can see is p(t) = (v(t))2 /R
when rearranged to v(t) = ....

No power of Pi. :uhh:
