During the discharge of a battery, the current in the circuit flows from the positive to the negative electrode. According to Ohm’s law, this means that the current is proportional to the electric field, which says that current flows from a positive to negative electric potential. But what ...
resistance, in electricity, property of an electric circuit or part of a circuit that transforms electric energy into heat energy in opposing electric current. Resistance involves collisions of the current-carrying charged particles with fixed particles that make up the structure of the conductors. Res...

In summary, when a key in a circuit is open, no current flows through the circuit. This is because an open circuit creates a break in the electrical path, preventing the movement of electrons. Consequently, devices connected to the circuit will not function until the key is closed, allowing...
The inductance saturated state affects the detector circuit state; a delay line follows the detector circuit; the circuit through which the line current flows contains a series circuit consisting of the above inductance and a light emitting diode with a resistor in parallel. The detector circuit ...
Define alternating current. alternating current synonyms, alternating current pronunciation, alternating current translation, English dictionary definition of alternating current. n. Abbr. AC An electric current that reverses direction in a circuit at re
If the current through a circuit is too weak, we can use LED because it glows even when a weak electric current flows through it. View Solution Q2 Unlike electric bulb, LED glows even when a weak current flows through it. View Solution Q3 __ glows even when a weak electri...
Resistor, electrical component that opposes the flow of either direct or alternating current, employed to protect, operate, or control the circuit. Voltages can be divided with the use of resistors, and in combination with other components resistors can
In the previous section, we looked at a simple circuit using a battery maintaining a constant electrical potential or voltage that resulted in a constant current through the circuit. This is referred to as a direct current (dc) circuit because the current is constant and flows only in one dir...
