Do bulbs in series have the same brightness? Placing cells in series increases the voltage in the circuit by 1.5 V for each cell. Increasing the number of bulbs in a series circuit decreases the brightness of the bulbs. In a series circuit, the voltage is equally distributed among all of the bulbs. Bulbs in […]
What is flux in electric field?
What is flux in electric field? Electric flux, property of an electric field that may be thought of as the number of electric lines of force (or electric field lines) that intersect a given area. The negative flux just equals in magnitude the positive flux, so that the net, or total, electric flux is zero. […]

What happens to capacitors at low frequencies?
What happens to capacitors at low frequencies? At very low frequencies, such as 1Hz our 220nF capacitor has a high capacitive reactance value of approx 723.3KΩ (giving the effect of an open circuit). At very high frequencies such as 1Mhz the capacitor has a low capacitive reactance value of just 0.72Ω (giving the effect of […]
What can a firewall not prevent?
What can a firewall not prevent? Users not going through the firewall: A firewall can only restrict connections that go through it.

How does electrostatic occur?
How does electrostatic occur? Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged. The rubbing of certain materials against one another can transfer negative charges, or electrons. […]
