How do I calculate Volts per cm (V/cm) with the following given?
Two coaxial tubes with 20kV placed across them.
Inner tube (actutally solid rod) has an OD of .5" and a length of 4"
Outer tube has an OD of 1.00" and a length of 4"
Homework Equations
The Attempt at a Solution
I was going to calculate the Area of the inner and outer tubes and convert them to cm, then divide the total area by the applied voltage? Somehow I don't think that is right?
To calculate V/cm, divide the voltage (V) by the distance (cm). The resulting value will be in units of V/cm.
Yes, you can use any units for voltage and distance as long as they are consistent. For example, if the voltage is given in millivolts (mV) and the distance is given in meters (m), the resulting V/cm value will be in units of mV/m.
To calculate the average V/cm, first calculate the V/cm for each individual voltage and distance pair, then add all the values together and divide by the number of pairs. This will give you the average V/cm value.
No, V/cm is a scalar quantity and does not depend on the direction of the electric field. Therefore, you do not need to consider the direction when calculating V/cm.
To convert V/cm to other units of electric field, you can use the following conversion factors: 1 V/cm = 1,000 V/m = 0.01 kV/cm = 10 mV/mm. Simply multiply the V/cm value by the desired conversion factor to get the equivalent value in the new unit.
