How are current and voltage related to torque and speed of a …
Voltage and current are the essential components of power a.k.a. the ability to perform work. To do work by means of spinning machinery requires a rotary-acting force - a torque. The rate at which the work proceeds (introduce time) and the measurement becomes of power. More power - increase either current or voltage or both.
Why does voltage drop in a series circuit but current stays the same ...
$begingroup$ @yusufa22 No, the voltage difference between two points is the amount of work done by or on a charged particle per unit of charge as it travels between those points. I prefer to think of it in a more intuitive way though, rather than going to the clinical definitions, unless I''m writing some kind of physics paper: voltage is one of …
How does voltage affect a magnetic field?
A magnetic field is a phenomenon that can occur in one of two ways: it is induced by a current carrying wire, or it is generated naturally by the charge arrangement in a ferrous material. That said, voltage is not exactly directly related to a magnetic field. However, because current is a result of a voltage in a circuit, fluctuations in applied …

Why does increasing voltage increase current? [duplicate]
The difference in electric potential energy (per charge) between two points is what we have given the name voltage. Thus, the voltage directly tells us which way charges want to move - and if they can, then they will speed up in that direction, so the current will increase. This is Ohm''s law.
When current flows from a battery, does voltage decrease?
I understand voltage to be a potential for electrons to be pushed through a circuit. However, in a battery, you have an electron build-up that creates the voltage. Once current begins to flow, electrons are now moving through the circuit. Does this mean that the voltage actually begins to decrease as a direct result of current flow?

19.3: Resistance and Resistors
Voltage Drop: The voltage drop across a resistor in a simple circuit equals the voltage output of the battery. Additional insight is gained by solving I=V/R for V, yielding V=IR. This expression for V can be interpreted as the voltage drop across a resistor produced by the flow of current I.

Physicist: Chemical batteries use a pair of chemical reactions to move charges from one terminal to the other with a fixed voltage, usually 1.5 volts for most batteries you can buy in the store (although there are other kinds of batteries).The chemicals in a battery litterally strip charge away from one terminal and deposite charge on the …
19.2: Electric Current
The electrical driving force across the terminals of a cell is known as the terminal voltage (difference) and is measured in volts. When a battery is connected to a circuit, the electrons from the anode travel through the circuit toward the cathode in a direct circuit. The voltage of a battery is synonymous with its electromotive force, or emf.
