Consider two isolated, charged conducting spheres: a large sphere and a second smaller sphere with a radius 8 times smaller than that of the large sphere, but with 4 times as much charge. (a) Calculate the ratio of the electric potential at the surface of the large sphere to that of the small sphere. (b) Calculate the ratio of the magnitudes of the electric fields at the surface of the large sphere to that of the small sphere.

What is the current through resistor r2

The three resistors are identical with R1 = R2 = R3= 160 ?, and the battery voltage is 50 V. What is the current through resistor R2? R2 and R3 are parallel so these need to

What is the average current

When a nerve cell depolarizes, charge is transferred across the cell membrane, changing the potential difference. For a typical nerve cell, 9.0 pC of charge flows in a time

How much work has been done on the charges

1. How much charge has been transferred from the negative to the positive terminal? Express your answer using two significant figures. 2.How much work has been done on the c

Calculate the magnitude of this decrease

Although an ideal voltmeter has an infinite internal resistance, this theoretical ideal is usually not met in practice. The voltmeter has an internal resistance of 8 x 10^9
