1. A 50. 0 Ω resistance has a voltage v = 115.0 sin 185t (V). Find the corresponding current i and power p.

2. Voltage(V)=current(I)*resistance(R)

3. I don't know what 115.0 and 185 are..? Except that all is well..

Please tell me what are the parameters in V equation in the problem..

115.0 is the amplitude of the voltage, units are (or should be) volts.

185 is the angular frequency for the sine function. It's units are (or should be) radians/second.
