What is voltage practically in a circuit? Burraq Engineering Solutions Answered Dec 23, 2021 Voltages in circuits The electrical voltage indicates how strong the drive of the electrical current is. It is measured in volts. If there are several components (resistors, light bulbs, coils, ...) in a circuit with an electrical source, they can be connected in series or in parallel with one another. The voltage applied to the individual components depends on the type of circuit and the electrical resistance of the component in question. The electrical voltage indicates how strong the drive of the electrical current is. It is measured in volts. As measuring instruments used voltmeters. If there are several components (resistors, light bulbs, coils, ...) in a circuit with an electrical source, they can be connected in series or in parallel with one another. Series connection (unbranched circuit) When components are connected in series, the total voltage is distributed over the individual components (Fig. 2). The total stress is equal to the sum of the partial stresses. The following applies: U=U1+U2+ ... +Un The amount of partial voltage that is applied to the individual component depends on the electrical resistance of the component. This results from the fact that the current strength in an unbranched circuit is constant and according to Ohm's law at I = constant U~ R is. This means: the component with the greater electrical resistance carries the greater voltage.
Are two components with the resistors R.1 other R.2 connected in series, this is how the partial voltages behave U1 other U2 like the electrical resistances. The following applies: U1/U2=R1/R2 This equation is also known as the voltage divider rule. If electrical sources are connected in series, the voltages of the individual sources add up to the total voltage. If you switch z. B. three mono cells with a voltage of 1.5 V each in a row, the total voltage is 4.5 V. Voltages in the unbranched circuit Parallel connection (branched circuit) When components are connected in parallel, the voltage across all of these components is the same. The following applies: U=U1=U2= ... =Un
Therefore z. B. also connected the devices in the household in parallel. This ensures that the operating voltage of 230 V is applied to each of the devices or to each incandescent lamp. Voltages in the branched circuit Upvote my answer if you like it
