If given the capacitance in (pF), how do you find the electric field (V/m)?

In summary, capacitance is the measure of an object's ability to store electric charge and is directly related to the electric field. The formula for finding electric field from capacitance is E = Q/C or E = V/d, where E is the electric field, Q is the charge, C is the capacitance, and d is the distance between charged plates. To find the electric field from capacitance, you will need to know the capacitance value, charge, and possibly the distance between plates. As capacitance increases, the electric field decreases, and vice versa. While capacitance and electric field cannot be measured directly, they can be calculated using specific formulas and measurements.

What is the equation or conversion factor?

The potential difference across a capacitor will be QC, where Q is the charge and
C the capacitance, and then the field strength between the plates will be QC/d, where
d is the distance between the plates

What is the equation or conversion factor?

Since capacitance and electric field are two different things then "conversion factor" is not really the right term to use. It's a bit like asking what is the conversion factor between mass in micrograms and speed.
 

1) What is capacitance and how is it related to electric field?

Capacitance is the measure of an object's ability to store electric charge. It is directly related to the electric field, as the strength of the electric field is proportional to the amount of charge stored in the object.

2) Can you explain the formula for finding electric field from capacitance?

The formula for finding electric field from capacitance is E = Q/C, where E is the electric field in volts per meter (V/m), Q is the charge in coulombs (C), and C is the capacitance in picofarads (pF). This formula can also be written as E = V/d, where V is the voltage in volts (V) and d is the distance between the charged plates in meters (m).

3) What information do I need to have in order to find the electric field from capacitance?

In order to find the electric field from capacitance, you will need to know the capacitance value in picofarads (pF) and the charge in coulombs (C) that is stored in the object. You may also need to know the distance between the charged plates in meters (m) if you are using the formula E = V/d.

4) How does the electric field change as capacitance changes?

As the capacitance increases, the electric field decreases. This is because an object with a higher capacitance has the ability to store more charge, which results in a lower electric field strength. Similarly, as capacitance decreases, the electric field increases.

5) Can capacitance and electric field be measured directly?

Capacitance and electric field cannot be measured directly, but they can be calculated using specific formulas and measurements. For example, capacitance can be calculated by measuring the charge and voltage of an object, and electric field can be calculated by measuring the charge and distance between two charged plates.
