Electric power is defined by the equation P= VI, where P stands for power, V stands for voltage, and I stands for current. Using Ohm's law, V = IR, we can substitute this for voltage in the original equation for power to write the equation for electric power in terms of current: P =I°R.

Slope=9.05 mA Please answer the second question. Now let's try some calculations on your slope. Divide the value of your slope by 1000. This will convert the units from milliamps per Volt to Amps per Volt. 9.05/1000=9.05*10^-3 A/V 2. Take the inverse of your slope, which will give a unit of Volts per Amp.

Hi I'm given the diameter of the sphere is 25cm. An electric pen brought near this sphere causes a voltage of 5000 V. The distance between the sphere and the pen is 14cm. The pen itself is measured at 25cm. they want to know what is the charge on the sphere? Please break it down so I can understand. The last answer had the wrong diameter calculated into the problem and was missing what formulas they used for each problem and how they solved it in steps.
