Calculate the electric field (in V/m) between two parallel plates connected to a 45 V battery if the plates are separated by a)

Sonja [21]

Answer:

Explanation:

Given

Voltage of battery $V=45\ V$

electric field(E) is given by

$E=|-\frac{dV}{dx}|$

i.e. Change in Potential over a distance x

(a)When Plate are separated by 3 cm apart

$E=|\frac{45}{3\times 10^{-2}}|$

$E=1500\ V/m$

(b)When Plates are 5 cm apart

$E=|-\frac{45}{5\times 10^{-2}}|$

$E=900\ V/m$

Force on electron is given by

$F=charge\times Electric\ Field$

$F=q\times E$

For case a

$F=1.6\times 10^{-19}\times 1500$

$F=24\times 10^{-17}\ N$

(b) $F=1.6\times 10^{-19}\times 900=14.4\times 10^{-17}\ N$

A light bulb has a power output of 80 W and it has been left on for 90 seconds. How much work was done?

Karo-lina-s [1.5K]

7200 joules of heat and light energy was dissipated into the air. But no work was done ... no force moved through no distance.
