Respuesta :
The current sources in the circuit are given, then the voltages are:
V₀ = -3v
V₁ = -1v
V₂ = -2v
V₃ = 8v
What is voltage?
Current circulates within a circuit due to the influence of voltage. A battery could be compared to a pump that circulates current in a circuit. Voltage can also be defined as the variation in electrical energy between two points on a circuit, which is a more complex definition.
When you want to raise the voltage in a circuit, you can either purchase batteries with various voltages or use multiple batteries. More current flows through a circuit when the voltage is higher. In the US and the UK, the standard household wiring voltage is 120V and 230V, respectively.
