Find the electric field strength between the plates of a parallel plate capacitor if 100 mV are applied across
the plates and the plates are 2 mm apart ?
To find the electric field strength between the plates of a parallel plate capacitor, you can use the formula:
Electric field strength (E) = Voltage (V) / Distance between plates (d)
Given that 100 mV (millivolts) are applied across the plates and the plates are 2 mm (millimeters) apart, we need to convert the values to the appropriate SI units before plugging them into the formula.
1 mV = 0.001 V (since 1 millivolt is equal to 0.001 volts)
1 mm = 0.001 m (since 1 millimeter is equal to 0.001 meters)
Now we can substitute these values into the formula:
Electric field strength (E) = 0.1 V / 0.002 m
Simplifying, we get:
Electric field strength (E) = 50 V/m
Therefore, the electric field strength between the plates of the parallel plate capacitor is 50 volts per meter (V/m).
