Commonly produced by sources of stored energy such as batteries. Sources of dc voltage have positive and negative terminals. Terminals establish polarity in a circuit, and polarity can be used to determine if a circuit is dc or ac. Commonly used in battery-powered portable equipment (autos, fla...
1. Definition of a Battery: A battery is a device that stores and provides electrical energy. It acts as a source of electricity. 2. Composition of a Battery: Batteries are typically made up of one or more electrochemical cells. 3. Understanding Electrochemical Cells: Electrochemical cells are...
Electric motors can be powered bydirect current(DC) sources, such as batteries orrectifiers. Or by alternating current (AC) sources, such as inverters,electric generators, or a power grid. Motors are the reason we have many of the technologies we enjoy in the 21st century. ...
<p><strong>Step-by-Step Solution:</strong></p><p>1. <strong>Definition of EMF</strong>: The Electromotive Force (EMF) of a cell is defined as the voltage or electrical potential difference between the two electrodes (anode and cathode) of an electroc
Voltage is the pressure from an electrical circuit’s power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.
What is the emf of the battery in the circuit shown below? Given, I = 1.75 A. Kirchhoff laws: Kirchhoff has given two laws related to current and voltage in a circuit; Kirchhoff's first law states that the net current coming in at a node is equal to the net current going o...
What is a chemoheterotroph and how does it obtain nutrition and energy? What is the metabolic function of vitamins A, B12, C, D3, and E? What kind of energy is primarily used to bring electricity to remote areas that are far from power lines? A. Kerosene. B. Batteries. C.Solar elec...
If the source of the EMF is removed, then the inductor will create a back EMF to try to maintain the current. If an alternating signal is applied, then it will impede the flow of current as a result of the inductive reactance.The basic parameters are used within the inductor, whatever ...
1) What is the Current ( I3 )? 2)What is wrong with the circuit? What is the peak voltage across a 4.0 u F capacitor? What is the terminal voltage and charge capacity of the following arrangement of batteries? Each battery delivers 6 Volts and has 100 Ah charge capacity. The circuit...
In Figure (b), two tanks have different water levels, creating a pressure difference that causes water to flow from one tank to the other until the levels equalize. Similarly, if we connect two batteries through conducting wire with different voltage levels then charges can flow from the batt...
