Analyzing Potential Difference and Electric Field

Analyzing Potential Difference and Electric Field#

A parallel-plate capacitor has charge of magnitude 7.0  μC on each plate and capacitance 5.0  μF when there is air between the plates. The plates are separated by 1.0  mm. With the charge on the plates kept constant, a dielectric with κ= 3.0 is inserted between the plates, completely filling the volume between the plates.

Part 1#

What is the potential difference between the plates of the capacitor before the dielectric has been inserted?

Answer Section#

Please enter a numeric value.

Part 2#

What is the potential difference between the plates of the capacitor after the dielectric has been inserted?

Answer Section#

Please enter a numeric value.

Part 3#

What is the electrical field at the point midway between the plates before the dielectric is inserted?

Answer Section#

Please enter a numeric value.

Part 4#

What is the electrical field at the point midway between the plates after the dielectric is inserted?

Answer Section#

Please enter a numeric value.
